Method Details

getTypeName

public String getTypeName()

Description copied from interface: IStatement

Gets the type name of this statement for SQL generation.

Specified by:

getTypeName in interface IStatement

Returns:

the type name

appendOptions

public void appendOptions(StringBuilder sqlOption)

Description copied from interface: PgForeignOptionContainer

Appends SQL OPTIONS clause to StringBuilder.

Specified by:

appendOptions in interface PgForeignOptionContainer

Parameters:

sqlOption - the StringBuilder to append to

getAlterHeader

public String getAlterHeader()

Description copied from interface: PgForeignOptionContainer

Returns the ALTER statement header for this object.

Specified by:

getAlterHeader in interface PgForeignOptionContainer

Returns:

ALTER statement prefix (e.g., "ALTER FOREIGN TABLE table_name")

appendMoveDataSql

public void appendMoveDataSql(IStatement newCondition,
 SQLScript script,
 String tblTmpBareName,
 List<String> identityCols)

Description copied from interface: ITable

Adds commands to the script for move data from the temporary table to the new table, given the identity columns, and a command to delete the temporary table.

appendMoveDataSql in interface ITable

Overrides:

appendMoveDataSql in class PgAbstractTable

computeHash

public void computeHash(Hasher hasher)

Description copied from interface: IHashable
