Method Detail

getCurrentTimestampSelectString

public String getCurrentTimestampSelectString()

Description copied from class: Dialect

Retrieve the command used to retrieve the current timestamp from the database.

Overrides:

getCurrentTimestampSelectString in class PostgreSQL81Dialect

Returns:

The command.

getCurrentTimestampSQLFunctionName

public String getCurrentTimestampSQLFunctionName()

Description copied from class: Dialect

The name of the database-specific SQL function for retrieving the current timestamp.

Overrides:

getCurrentTimestampSQLFunctionName in class Dialect

Returns:

The function name.

registerResultSetOutParameter

public int registerResultSetOutParameter(CallableStatement statement,
                                int col)
                                  throws SQLException

Description copied from class: Dialect

Registers a parameter (either OUT, or the new REF_CURSOR param type available in Java 8) capable of returning ResultSet *by position*. Pre-Java 8, registering such ResultSet-returning parameters varied greatly across database and drivers; hence its inclusion as part of the Dialect contract.

Overrides:

registerResultSetOutParameter in class PostgreSQL81Dialect

Parameters:

statement - The callable statement.

col - The bind position at which to register the output param.

Returns:

The number of (contiguous) bind positions used.

Throws:

SQLException - Indicates problems registering the param.

getResultSet

public ResultSet getResultSet(CallableStatement ps)
                       throws SQLException

Description copied from class: Dialect

Given a callable statement previously processed by Dialect.registerResultSetOutParameter(java.sql.CallableStatement, int), extract the ResultSet from the OUT parameter.

Overrides:

getResultSet in class PostgreSQL81Dialect

Parameters:

ps - The callable statement.

Returns:

The extracted result set.

Throws:

SQLException - Indicates problems extracting the result set.

getSelectGUIDString

public String getSelectGUIDString()

Description copied from class: Dialect

Get the command used to select a GUID from the underlying database.

Optional operation.

Overrides:

getSelectGUIDString in class Dialect

Returns:

The appropriate command.
