Expected Behavior

CALL <database>.<schema>.TEST_PROCEDURE('test', 'test'); returns Success.

Actual Behavior

CALL <database>.<schema>.TEST_PROCEDURE('test', 'test'); gives error Error: invalid identifier 'SCHEMA_NAME' (line 13).

Steps to Reproduce

Create the resource with the above config, and run CALL <database>.<schema>.TEST_PROCEDURE('test', 'test');.

How much impact is this issue causing?

Medium

Additional Information

It seems the arguments in the procedure signature are defined with double quotes. The create statement from the above configuration -

CREATE OR REPLACE PROCEDURE <database>.<schema>.TEST_PROCEDURE("schema_name" VARCHAR(16777216), "table_name" VARCHAR(16777216))
RETURNS VARCHAR(16777216)
LANGUAGE SQL
STRICT
COMMENT='Test procedure'
EXECUTE AS CALLER
AS '  DECLARE
    source_table STRING;
    target_table STRING;
  BEGIN
    source_table := ''database.'' || schema_name || ''.'' || table_name;
    RETURN ''Success'';
  END;
';

I verified on the console that removing the double quotes from the procedure signature and then calling returns Success as expected.

In addition, it seems quoting schema_name and table_name in the procedure definition of the resource fixes the issue -

resource "snowflake_procedure_sql" "proc_create_stream_data_table" {
  name                = "TEST_PROCEDURE"
  database            = "<database>"
  schema              = "<schema>"
  comment             = "Test procedure"
  return_type         = "VARCHAR"
  execute_as          = "CALLER"
  null_input_behavior = "RETURNS NULL ON NULL INPUT"
  arguments {
    arg_name      = "schema_name"
    arg_data_type = "varchar"
  }
  arguments {
    arg_name      = "table_name"
    arg_data_type = "varchar"
  }
  procedure_definition = <<EOT
  DECLARE
    source_table STRING;
    target_table STRING;
  BEGIN
    source_table := 'database.' || "schema_name" || '.' || "table_name";
    RETURN 'Success';
  END;
  EOT

I don't think this was necessary in previous versions of the provider, as calling the procedure worked previously.

Would you like to implement a fix?

• Yeah, I'll take it 😎

Hi @jdoldis 👋

You are right - this happens because arg_name is quoted (by the provider) and is actually lowercase in this example, but it is not quoted in the definition. The behavior is expected. Please either use uppercase arg_name or quote the arg name in procedure_definition.

I think this is related to all resources with fields like body, definition, etc. We will add a note to the documentation for the relevant resources.

Perfect, thanks @sfc-gh-jmichalak !

Hey @jdoldis. We have released v1.0.1 on Friday. We added clarifications in the migration guide and the registry docs. Please check if the docs are clearer now.
