Member Function Documentation

Explain()

perf_postgres::Explain	(		$sql,
			$partial = false )

Reimplemented from adodb_perf.

optimizeDatabase()

adodb_perf::optimizeDatabase ( )

inherited

Reorganise current database.

Default implementation loops over all MetaTables() and optimize each using optmizeTable()

Author

Markus Staab

Return values

bool	true on success, false on error

Examples

/home/runner/work/phpdoc/phpdoc/.moodle/lib/adodb/adodb-perf.inc.php.

OptimizeTable()

adodb_perf::OptimizeTable ( $table, $mode = ADODB_OPT_LOW )

inherited

Reorganise the table-indices/statistics/.

. depending on the given mode. Default Implementation throws an error.

Parameters

string	table name of the table to optimize
int	mode optimization-mode ADODB_OPT_HIGH for full optimization ADODB_OPT_LOW for CPU-less optimization Default is LOW ADODB_OPT_LOW

Author

Markus Staab

Return values

bool	true on success, false on error

optimizeTable()

perf_postgres::optimizeTable	(		$table,
			$mode = ADODB_OPT_LOW )

adodb_perf\optimizeTable()

Tables()

adodb_perf::Tables ( $orderby = '1' )

inherited

Reimplemented in perf_db2.
