configures connector to take data based on provided SQL text.

$conn->render_sql($sql,$id,$text,$extra,$relation_id);

Parameters:

• $sql - any sql code, which will be used as a base for data selection.
• $id - name of id field.
• $text - comma separated list of data fields.
• $extra - comma separated list of extra fields, optional.
• $relation_id - used for building hierarchy in case of Tree and TreeGrid.

configures connector to take data based on provided SQL text.
Works similar to render_sql, but have 2 differences:

1. Uses provided sql exactly as it is;
2. Can be used only for data loading (for data saving you can use separate connector, event handlers, or custom model).

The method can be used to call stored procedures in the database.

$conn->render_complex_sql($sql,$id,$text,$extra,$relation_id);

Parameters:

• $sql - any sql code, which will be used as a base for data selection or the name of a stored procedure.
• $id - name of id field.
• $text - comma separated list of data fields.
• $extra - comma separated list of extra fields, optional.
• $relation_id - used for building hierarchy in case of Tree and TreeGrid.

See Also:

• render_sql
• render_table
• Basic concepts

configures connector to take data from single table.

$conn->render_table($table,$id,$text,$extra,$relation);

Parameters:

• $table - name of table.
• $id - name of id field.
• $text - comma separated list of data fields.
• $extra - comma separated list of extra fields, optional.
• $relation_id - used for building hierarchy in case of Tree and TreeGrid.

Description:

• If you want to render all fields from DB ( except of identity field), you can use simplified command:
  
  

  $conn->render_table($table);

Parameters:

• number of data items which should be loaded
