PG_UPDATE(3) PG_UPDATE(3) pg_update - Update table SYNOPSIS
mixed pg_update (resource $connection, string $table_name, array $data, array $condition, [int $options = PGSQL_DML_EXEC]) DESCRIPTION
pg_update(3) updates records that matches condition with data. If options is specified, pg_convert(3) is applied to data with specified options. PARAMETERS
o $connection - PostgreSQL database connection resource. o $table_name - Name of the table into which to update rows. o $data - An array whose keys are field names in the table $table_name, and whose values are what matched rows are to be updated to. o $condition - An array whose keys are field names in the table $table_name, and whose values are the conditions that a row must meet to be updated. o $options - Any number of PGSQL_CONV_FORCE_NULL, PGSQL_DML_NO_CONV, PGSQL_DML_ESCAPE, PGSQL_DML_EXEC, PGSQL_DML_ASYNC or PGSQL_DML_STRING combined. If PGSQL_DML_STRING is part of the $options then query string is returned. When PGSQL_DML_NO_CONV or PGSQL_DML_ESCAPE is set, it does not call pg_convert(3) internally. RETURN VALUES
Returns TRUE on success or FALSE on failure. Returns string if PGSQL_DML_STRING is passed via $options. EXAMPLES
Example #1 pg_update(3) example <?php $db = pg_connect('dbname=foo'); $data = array('field1'=>'AA', 'field2'=>'BB'); // This is safe, since $_POST is converted automatically $res = pg_update($db, 'post_log', $_POST, $data); if ($res) { echo "Data is updated: $res "; } else { echo "User must have sent wrong inputs "; } ?> CHANGELOG

SQLITE_FETCH_COLUMN_TYPES(3) SQLITE_FETCH_COLUMN_TYPES(3) sqlite_fetch_column_types - Return an array of column types from a particular table SYNOPSIS
array sqlite_fetch_column_types (string $table_name, resource $dbhandle, [int $result_type = SQLITE_ASSOC]) DESCRIPTION
Object oriented style (method): array SQLiteDatabase::fetchColumnTypes (string $table_name, [int $result_type = SQLITE_ASSOC]) sqlite_fetch_column_types(3) returns an array of column data types from the specified $table_name table. PARAMETERS
o $table_name - The table name to query. o $dbhandle - The SQLite Database resource; returned from sqlite_open(3) when used procedurally. This parameter is not required when using the object-oriented method. o $result_type - The optional $result_type parameter accepts a constant and determines how the returned array will be indexed. Using SQLITE_ASSOC will return only associative indices (named fields) while SQLITE_NUM will return only numerical indices (ordinal field numbers). SQLITE_ASSOC is the default for this function. RETURN VALUES
Returns an array of column data types; FALSE on error. The column names returned by SQLITE_ASSOC and SQLITE_BOTH will be case-folded according to the value of the sqlite.assoc_case configuration option. CHANGELOG
