    I have two tables and I want to delete records from one table for which there is no matching records in second table. Now the question is How to delete records using MINUS SQL Statement? Please explain with example

    DELETE from Table1

    (select COL1 from Table1
    MINUS
    select Col2 from Table 2)

    Table1 will have extra records compared to table2 so I want to delete extra records from table 1

    tried Expect function but it gave 00933. 00000 -  "SQL command not properly ended" to be more precise my script is

    Delete from Table1
    where Not Exact
    (select col1 from Table1
    MINUS
    select concat('A_',col1) from Table2 where 
    Col2 = '748' and
    Col3 = 'D' and
    Col4 = 'Account')

    I should have been more clearer , what is the product used to run this script? 

    T-SQL is programming language for SQL Server product , from your script it looks like doesn't belong to SQL Server. In that case , this may not be right forum for this question.

    The error message suggests an Oracle script. This is a Microsoft SQL Server forum. I suggest you post Oracle questions to https://stackoverflow.com/questions/tagged/oracle with an oracle tag.

    Oracle Sql Developer Version 4.1.1.19

    Then ask this in an Oracle forum, as Dan already wrote.
