query-export-tool

Tool export query in CSV and XLS / XLSX format

1 Quickstart

1.1 Create a sample query catalog

<query-catalog-config>

	<query-catalog id="main-catalog">
		<query id="Q001" sql="SELECT * FROM  test_export" outputFormat="csv" csvSeparator=";" outputFile="target/catalog_test_001.csv"/>
		<query id="Q002" sql="SELECT * FROM  test_export" outputFormat="csv" outputFile="target/catalog_test_002.csv"/>
		<query id="Q003" sql="SELECT * FROM  test_export" outputFormat="html" outputFile="target/catalog_test_003.html" createPath="1"/>
		<query id="Q004" sql="SELECT * FROM  test_export" outputFormat="xls" outputFile="target/catalog_test_004.xls" xlsResize="1"/>
		<query id="Q005" sql="SELECT * FROM  test_export" outputFormat="xlsx" outputFile="target/catalog_test_004.xlsx" xlsTemplate="src/test/resources/template/test_template.xlsx" />
	</query-catalog>

</query-catalog-config>

1.2 Load and use the catalog

		QueryConfigCatalog catalog = QueryConfigCatalog.loadQueryConfigCatalogSafe( "cl://sample/query-catalog-sample.xml" );
		try ( Connection conn = ... ) {
			catalog.handle( conn , "main-catalog", "Q001");
		}

2 Formats

2.1 HTML format

HTML format is handled with core I/O API, no dependency needed.

2.2 CSV format

CSV Format needs OpenCSV dependency, which is automatically included by default when importing query-export-tool dependency.

If needed it can be added in explicit way :

		<dependency>
			<groupId>com.opencsv</groupId>
			<artifactId>opencsv</artifactId>
			<version>${opencsv-version}</version>
		</dependency>

2.3 XLS/XLSX formats

XLS/XLSX Formats needs Apache POI dependency, which is NOT automatically included by default when importing query-export-tool dependency :

		<dependency>
			<groupId>org.apache.poi</groupId>
			<artifactId>poi-ooxml</artifactId>
			<version>${poi-version}</version>
		</dependency>
