wpdb::_insert_replace_helper() public WP 3.0.0
Helper function for insert and replace.
Runs an insert or replace query based on $type argument.
{} It's a method of the class: wpdb{}
No Hooks.
Return
Int/false. The number of rows affected, or false on error.
Usage
global $wpdb; $wpdb->_insert_replace_helper( $table, $data, $format, $type );
- $table(string) (required)
- Table name.
- $data(array) (required)
- Data to insert (in column => value pairs). Both $data columns and $data values should be "raw" (neither should be SQL escaped). Sending a null value will cause the column to be set to NULL - the corresponding format is ignored in this case.
- $format(array/string)
- An array of formats to be mapped to each of the value in $data. If string, that format will be used for all of the values in $data. A format is one of '%d', '%f', '%s' (integer, float, string). If omitted, all values in $data will be treated as strings unless otherwise specified in wpdb::$field_types.
Default: null - $type(string)
- Type of operation. Possible values include 'INSERT' or 'REPLACE'.
Default: 'INSERT'
