Additionally, it includes tests for UUID, JSON, BigDecimal, and Rust Decimal types, further improving the coverage of the ODBC implementation. --- sqlx-core/src/odbc/arguments.rs | 265 ++++++++++++++++++++++++++++++++ sqlx-core/src/odbc/type.rs | 185 ++++++++++++++++++++++ sqlx-core/src/odbc/type_info.rs | 2 + sqlx-core/src/odbc/value.rs | 153 ++++++++++++++++++ test.sh | 2 +- tests/odbc/odbc.rs | 239 ++++++++++++++++++++++++++++ 6 files changed, 845 insertions(+), 1 deletion(-) diff --git a/sqlx-core/src/odbc/arguments.rs b/sqlx-core/src/odbc/arguments.rs index f73f8fda87..aef5d79d9a 100644 --- a/sqlx-core/src/odbc/arguments.rs +++ b/sqlx-core/src/odbc/arguments.rs @@ -118,6 +118,271 @@ impl<'q> Encode<'q, Odbc> for Vec { } } +impl<'q> Encode<'q, Odbc> for &'q [u8] { + fn encode(self, buf: &mut Vec>) -> crate::encode::IsNull { + buf.push(OdbcArgumentValue::Bytes(self.to_vec()));

It also refines compatibility checks in the `Type` trait implementations for various data types, ensuring better handling of character data and improving overall robustness in ODBC interactions. --- Cargo.toml | 5 + sqlx-core/src/odbc/arguments.rs | 32 +++-- sqlx-core/src/odbc/type.rs | 39 ++++-- sqlx-core/src/odbc/value.rs | 2 +- sqlx-test/src/lib.rs | 7 ++ tests/odbc/odbc.rs | 85 +++++-------- tests/odbc/types.rs | 208 ++++++++++++++++++++++++++++++++ 7 files changed, 300 insertions(+), 78 deletions(-) create mode 100644 tests/odbc/types.rs diff --git a/Cargo.toml b/Cargo.toml index 5d3fdcc2ca..bbecfd08cc 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -336,6 +336,11 @@ name = "odbc" path = "tests/odbc/odbc.rs" required-features = ["odbc"] +[[test]] +name = "odbc-types" +path = "tests/odbc/types.rs" +required-features = ["odbc"] + [[test]] name = "mssql-types" path = "tests/mssql/types.rs" diff --git a/sqlx-core/src/odbc/arguments.rs b/sqlx-core/src/odbc/arguments.rs index aef5d79d9a..e3b56b8591 100644 --- a/sqlx-core/src/odbc/arguments.rs +++ b/sqlx-core/src/odbc/arguments.rs @@ -264,48 +264,64 @@ mod chrono_encode { impl<'q> Encode<'q, Odbc> for NaiveDateTime { fn encode(self, buf: &mut Vec>) -> crate::encode::IsNull { - buf.push(OdbcArgumentValue::Text(self.format("%Y-%m-%d %H:%M:%S").to_string()));

This change simplifies the structure of the ODBC module and enhances maintainability. The previous implementations in the arguments and value files have been removed, and the necessary imports have been adjusted accordingly. --- sqlx-core/src/odbc/arguments.rs | 365 +------------------------ sqlx-core/src/odbc/mod.rs | 2 +- sqlx-core/src/odbc/type.rs | 336 ----------------------- sqlx-core/src/odbc/types/bigdecimal.rs | 42 +++ sqlx-core/src/odbc/types/bool.rs | 56 ++++ sqlx-core/src/odbc/types/bytes.rs | 73 +++++ sqlx-core/src/odbc/types/chrono.rs | 195 +++++++++++++ sqlx-core/src/odbc/types/decimal.rs | 42 +++ sqlx-core/src/odbc/types/float.rs | 89 ++++++ sqlx-core/src/odbc/types/int.rs | 281 +++++++++++++++++++ sqlx-core/src/odbc/types/json.rs | 34 +++ sqlx-core/src/odbc/types/mod.rs | 20 ++ sqlx-core/src/odbc/types/str.rs | 71 +++++ sqlx-core/src/odbc/types/uuid.rs | 45 +++ sqlx-core/src/odbc/value.rs | 267 +----------------- 15 files changed, 951 insertions(+), 967 deletions(-) delete mode 100644 sqlx-core/src/odbc/type.rs create mode 100644 sqlx-core/src/odbc/types/bigdecimal.rs create mode 100644 sqlx-core/src/odbc/types/bool.rs create mode 100644 sqlx-core/src/odbc/types/bytes.rs create mode 100644 sqlx-core/src/odbc/types/chrono.rs create mode 100644 sqlx-core/src/odbc/types/decimal.rs create mode 100644 sqlx-core/src/odbc/types/float.rs create mode 100644 sqlx-core/src/odbc/types/int.rs create mode 100644 sqlx-core/src/odbc/types/json.rs create mode 100644 sqlx-core/src/odbc/types/mod.rs create mode 100644 sqlx-core/src/odbc/types/str.rs create mode 100644 sqlx-core/src/odbc/types/uuid.rs diff --git a/sqlx-core/src/odbc/arguments.rs b/sqlx-core/src/odbc/arguments.rs index e3b56b8591..4e2706ceb0 100644 --- a/sqlx-core/src/odbc/arguments.rs +++ b/sqlx-core/src/odbc/arguments.rs @@ -34,370 +34,7 @@ impl<'q> Arguments<'q> for OdbcArguments<'q> { } } -impl<'q> Encode<'q, Odbc> for i32 { - fn encode(self, buf: &mut Vec>) -> crate::encode::IsNull { - buf.push(OdbcArgumentValue::Int(self as i64));

It includes the addition of ODBC-specific types, connection options, and implementations for encoding and decoding various data types. New tests have been added to ensure robust functionality and compatibility with ODBC interactions. The Cargo.toml file has also been updated to include the new ODBC test suite, enhancing overall test coverage. --- Cargo.toml | 5 + sqlx-core/src/any/arguments.rs | 27 + sqlx-core/src/any/column.rs |

The new structure enhances maintainability by streamlining the generation of trait implementations based on enabled features, reducing code duplication while ensuring comprehensive support for various database combinations. --- sqlx-core/src/any/column.rs | 194 +++++++++++------------------------- sqlx-core/src/any/decode.rs | 151 +++++++++++----------------- sqlx-core/src/any/encode.rs | 151 +++++++++++----------------- 3 files changed, 174 insertions(+), 322 deletions(-) diff --git a/sqlx-core/src/any/column.rs b/sqlx-core/src/any/column.rs index a32163a999..9e9fc836e4 100644 --- a/sqlx-core/src/any/column.rs +++ b/sqlx-core/src/any/column.rs @@ -88,148 +88,66 @@ impl Column for AnyColumn { } } -// Macro to generate AnyColumnIndex trait and impl based on enabled features -macro_rules! define_any_column_index { -

The `execute_stream` method now directly accepts an optional `OdbcArguments` type, streamlining the execution process and improving code clarity. Unused methods related to argument handling have been removed, enhancing maintainability. --- sqlx-core/src/odbc/connection/executor.rs | 8 +-- sqlx-core/src/odbc/connection/worker.rs | 63 ++++------------------- 2 files changed, 11 insertions(+), 60 deletions(-) diff --git a/sqlx-core/src/odbc/connection/executor.rs b/sqlx-core/src/odbc/connection/executor.rs index 272dcafc98..bdb127f235 100644 --- a/sqlx-core/src/odbc/connection/executor.rs +++ b/sqlx-core/src/odbc/connection/executor.rs @@ -22,13 +22,9 @@ impl<'c> Executor<'c> for &'c mut OdbcConnection { E: Execute<'q, Self::Database> + 'q, { let sql = query.sql().to_string(); - let mut args = query.take_arguments(); + let args = query.take_arguments(); Box::pin(try_stream! { - let rx = if let Some(a) = args.take() { - self.worker.execute_stream_with_args(&sql, a.values).await? - } else { - self.worker.execute_stream(&sql).await? - }; + let rx = self.worker.execute_stream(&sql, args).await?; while let Ok(item) = rx.recv_async().await { r#yield!(item?); } diff --git a/sqlx-core/src/odbc/connection/worker.rs b/sqlx-core/src/odbc/connection/worker.rs index f55f8cc7bb..4e0de98e31 100644 --- a/sqlx-core/src/odbc/connection/worker.rs +++ b/sqlx-core/src/odbc/connection/worker.rs @@ -6,7 +6,8 @@ use futures_intrusive::sync::Mutex; use crate::error::Error; use crate::odbc::{ - OdbcArgumentValue, OdbcColumn, OdbcConnectOptions, OdbcQueryResult, OdbcRow, OdbcTypeInfo, + OdbcArgumentValue, OdbcArguments, OdbcColumn, OdbcConnectOptions, OdbcQueryResult, OdbcRow, + OdbcTypeInfo, }; #[allow(unused_imports)] use crate::row::Row as SqlxRow; @@ -42,11 +43,7 @@ enum Command { }, Execute { sql: Box, - tx: flume::Sender, Error>>, - }, - ExecuteWithArgs { - sql: Box, - args: Vec, + args: Option, tx: flume::Sender, Error>>, }, } @@ -112,13 +109,8 @@ impl ConnectionWorker { let _ = tx.send(()); return; } - Command::Execute { sql, tx } => { - with_conn(&shared, |conn| execute_sql(conn, &sql, &tx)); - } - Command::ExecuteWithArgs { sql, args, tx } => { - with_conn(&shared, |conn| { - execute_sql_with_params(conn, &sql, args, &tx) - }); + Command::Execute { sql, args, tx } => { + with_conn(&shared, |conn| execute_sql(conn, &sql, args, &tx)); } } } @@ -178,26 +170,11 @@ impl ConnectionWorker { pub(crate) async fn execute_stream( &mut self, sql: &str, + args: Option, ) -> Result, Error>>, Error> { let (tx, rx) = flume::bounded(64); self.command_tx .send_async(Command::Execute { - sql: sql.into(), - tx, - }) - .await - .map_err(|_| Error::WorkerCrashed)?; - Ok(rx) - } - - pub(crate) async fn execute_stream_with_args( - &mut self, - sql: &str, - args: Vec, - ) -> Result, Error>>, Error> { - let (tx, rx) = flume::bounded(64); - self.command_tx - .send_async(Command::ExecuteWithArgs { sql: sql.into(), args, tx, @@ -232,32 +209,10 @@ fn exec_simple(shared: &Shared, sql: &str) -> Result<(), Error> { fn execute_sql( conn: &odbc_api::Connection<'static>, sql: &str, + args: Option, tx: &flume::Sender, Error>>, ) { - match conn.execute(sql, (), None) { - Ok(Some(mut cursor)) => { - let columns = collect_columns(&mut cursor); - if let Err(e) = stream_rows(&mut cursor, &columns, tx) { - let _ = tx.send(Err(e)); - return; - } - let _ = tx.send(Ok(Either::Left(OdbcQueryResult { rows_affected: 0 }))); - } - Ok(None) => { - let _ = tx.send(Ok(Either::Left(OdbcQueryResult { rows_affected: 0 }))); - } - Err(e) => { - let _ = tx.send(Err(Error::from(e))); - } - } -} - -fn execute_sql_with_params( - conn: &odbc_api::Connection<'static>, - sql: &str, - args: Vec, - tx: &flume::Sender, Error>>, -) { + let args = args.map(|a| a.values).unwrap_or_default(); if args.is_empty() { dispatch_execute(conn, sql, (), tx); return; @@ -265,7 +220,7 @@ fn execute_sql_with_params( let mut params: Vec> = Vec::with_capacity(args.len()); - for a in dbg!(args) { + for a in args { params.push(to_param(a)); } dispatch_execute(conn, sql, ¶ms[..], tx); From 4c0d4f274cab43819f1d2c60667bc673daedf3c0 Mon Sep 17 00:00:00 2001 From: lovasoa Date: Sun, 21 Sep 2025 03:19:56 +0200 Subject: [PATCH 35/92] chore: Update ODBC configuration and CI workflow for PostgreSQL support This commit modifies the ODBC configuration to use PostgreSQL Unicode and updates the CI workflow to run ODBC tests against PostgreSQL instead of SQLite.

It also simplifies the command processing logic and improves the handling of SQL execution results. Additionally, new tests have been added to validate the functionality of prepared statements and error handling for parameter counts. --- sqlx-core/src/odbc/connection/executor.rs | 6 +- sqlx-core/src/odbc/connection/worker.rs | 445 +++++++++++++--------- tests/any/odbc.rs | 36 ++ 3 files changed, 312 insertions(+), 175 deletions(-) diff --git a/sqlx-core/src/odbc/connection/executor.rs b/sqlx-core/src/odbc/connection/executor.rs index bdb127f235..45a32185f8 100644 --- a/sqlx-core/src/odbc/connection/executor.rs +++ b/sqlx-core/src/odbc/connection/executor.rs @@ -60,11 +60,11 @@ impl<'c> Executor<'c> for &'c mut OdbcConnection { 'c: 'e, { Box::pin(async move { - // Basic statement metadata: no parameter/column info without executing + let (_, columns, parameters) = self.worker.prepare(sql).await?; Ok(OdbcStatement { sql: Cow::Borrowed(sql), - columns: Vec::new(), - parameters: 0, + columns, + parameters, }) }) } diff --git a/sqlx-core/src/odbc/connection/worker.rs b/sqlx-core/src/odbc/connection/worker.rs index 4e0de98e31..0b713bf222 100644 --- a/sqlx-core/src/odbc/connection/worker.rs +++ b/sqlx-core/src/odbc/connection/worker.rs @@ -1,8 +1,6 @@ -use std::sync::Arc; use std::thread; use futures_channel::oneshot; -use futures_intrusive::sync::Mutex; use crate::error::Error; use crate::odbc::{ @@ -17,12 +15,6 @@ use odbc_api::{Cursor, CursorRow, IntoParameter, ResultSetMetadata}; #[derive(Debug)] pub(crate) struct ConnectionWorker { command_tx: flume::Sender, - pub(crate) shared: Arc, -} - -#[derive(Debug)] -pub(crate) struct Shared { - pub(crate) conn: Mutex>, // see establish for 'static explanation } enum Command { @@ -46,8 +38,13 @@ enum Command { args: Option, tx: flume::Sender, Error>>, }, + Prepare { + sql: Box, + tx: oneshot::Sender, usize), Error>>, + }, } + impl ConnectionWorker { pub async fn establish(options: OdbcConnectOptions) -> Result { let (establish_tx, establish_rx) = oneshot::channel(); @@ -55,65 +52,7 @@ impl ConnectionWorker { thread::Builder::new() .name("sqlx-odbc-conn".into()) .spawn(move || { - let (tx, rx) = flume::bounded(64); - - // Create environment and connect.
