setRemarksReporting

setRemarksReporting

public void setRemarksReporting(boolean reportRemarks)
Turns on or off the reporting of the REMARKS columns by the getTables and getColumns calls of the DatabaseMetaData interface.
The DatabaseMetaData calls getTables and getColumns are extremely slow if the REMARKS column has to be reported as this necessitates an expensive outer join so by default the JDBC driver does not report the REMARKS columns.

You can turn the reporting of REMARKS on by passing a true argument to this method. You turn it back off by passing a false argument.

Example where conn is your connection object:
((OracleConnection)conn).setRemarksReporting(true);

You can also control the reporting of REMARKS by passing a property named remarksReporting as true to the DriverManager.getConnection call.

Parameters:
reportRemarks - true if you want to turn on the reporting of the REMARKS columns and false otherwise.
