Example 5 with SybaseDatabase

use of liquibase.database.core.SybaseDatabase in project liquibase by liquibase.

the class CreateTableGeneratorTest method testAutoIncrementSybaseDatabaseWithSpecialCharacters.

@Test
public void testAutoIncrementSybaseDatabaseWithSpecialCharacters() throws Exception {
    for (Database database : TestContext.getInstance().getAllDatabases()) {
        if (database instanceof SybaseDatabase) {
            CreateTableStatement statement = new CreateTableStatement(CATALOG_NAME, "SCHEMA-NAME", "TABLE NAME");
            statement.addColumn("1ST_COLUMN_NAME", DataTypeFactory.getInstance().fromDescription("BIGINT{autoIncrement:true}", database), new AutoIncrementConstraint("1ST_COLUMN_NAME"));
            Sql[] generatedSql = this.generatorUnderTest.generateSql(statement, database, null);
            assertEquals("Error with " + database, "CREATE TABLE [SCHEMA-NAME].[TABLE NAME] ([1ST_COLUMN_NAME] BIGINT IDENTITY NULL)", generatedSql[0].toSql());
        }
    }
