B4J Question ABMaterial Generator

this morning as i was going through ABMaterial Helper i came across ABMGenerator and clicked on generate code button at the bottom of the page.I have studied the codes and I have created code module and called it DBM.

Sub ABMGenSQLInsert(SQL As SQL, Query As String, Args As List) As Int
Dim res As Int
Try
Select Case DatabaseType
Case 0
SQL.ExecNonQuery2(Query, Args)
res = ABMGenSQLSelectSingleResult(SQL, "SELECT last_insert_rowid()", Null)
Case 1
SQL.ExecNonQuery2(Query, Args)
res = ABMGenSQLSelectSingleResult(SQL, "SELECT LAST_INSERT_ID()", Null)
Case 2
Dim ABSQL As ABSQLExt
res = ABSQL.ExecNonQuery3(SQL, Query, Args)
End Select
Catch
Log(LastException)
res = DBERROR
End Try
Return res
End Sub

question in the above subroutine "ABSQLExt" am being informed it is missing as library
