Modifier and Type	Method	Description
protected boolean	batchDDL()	Whether this implementation shall use bates for DDL operations to create tables.
protected java.util.Map<TxDatabaseAdapter.NessieSqlDataType,java.lang.String>	databaseSqlFormatParameters()	Get database-specific 'strings' like column definitions for 'BLOB' column types.
protected java.lang.String	insertOnConflictDoNothing(java.lang.String insertSql)	Some RDBMS' just return an error when an INSERT/UPDATE/DELETE violates a constraint, like a primary key, but other RDBMS' like PostgreSQL do return an error and mark the whole transaction as failed.
protected boolean	metadataUpperCase()	Whether the database/JDBC-driver require schema-metadata-queries require upper-case names.

Method Detail

databaseSqlFormatParameters

protected java.util.Map<TxDatabaseAdapter.NessieSqlDataType,java.lang.String> databaseSqlFormatParameters()

Description copied from class: TxDatabaseAdapter

Get database-specific 'strings' like column definitions for 'BLOB' column types. Used as placeholders to format the DDL statements from TxDatabaseAdapter.allCreateTableDDL().

Specified by:

databaseSqlFormatParameters in class TxDatabaseAdapter

See Also:

TxDatabaseAdapter.NessieSqlDataType, TxDatabaseAdapter.allCreateTableDDL()

insertOnConflictDoNothing

protected java.lang.String insertOnConflictDoNothing(java.lang.String insertSql)

Description copied from class: TxDatabaseAdapter

Some RDBMS' just return an error when an INSERT/UPDATE/DELETE violates a constraint, like a primary key, but other RDBMS' like PostgreSQL do return an error and mark the whole transaction as failed. This function allows is meant to be implemented for RDBMS' that do mark the transaction as failed to modify an INSERT SQL statement to neither yield an error nor mark the transaction as failed.

Overrides:

insertOnConflictDoNothing in class TxDatabaseAdapter

metadataUpperCase

protected boolean metadataUpperCase()

Description copied from class: TxDatabaseAdapter

Whether the database/JDBC-driver require schema-metadata-queries require upper-case names.

Overrides:

metadataUpperCase in class TxDatabaseAdapter

batchDDL

protected boolean batchDDL()

Description copied from class: TxDatabaseAdapter

Whether this implementation shall use bates for DDL operations to create tables.

Overrides:

batchDDL in class TxDatabaseAdapter
