Belongs to Function Group: Database Access and Update

## Function

The `DELETE` statement is used to delete a record from a database.

### Hold Status

The use of the `DELETE` statement causes each record selected in the corresponding `FIND` or `READ` statement to be placed in exclusive hold.

Record hold logic is explained in the section Database Update - Transaction Processing (in the Programming Guide).

## Restriction

A `DELETE` statement cannot be specified in the same statement line as a `FIND`, `READ`, or `GET` statement.

## Syntax Description

Syntax Element | Description
--- | ---
`(r)` | Statement Reference: The notation `(r)` is used to reference the statement which was used to select/read the record to be deleted. If no statement reference is specified, the `DELETE` statement will reference the innermost active processing loop in which a database record was selected/read.

## Database-Specific Considerations

SQL Databases | The `DELETE` statement is used to delete a row from the database table. It corresponds with the SQL statement `DELETE WHERE CURRENT OF CURSOR-NAME`, that is, only the row which was read last can be deleted. With most SQL databases, a row that was read with a `FIND SORTED BY` or `READ LOGICAL` statement cannot be deleted.
XML Databases | The `DELETE` statement is used to delete an XML object from a database. For XML databases, this implies that only the record which was read last can be deleted.

## Examples

### Example 1

In this example, all records with the name `ALDEN` are deleted.

    ** Example 'DELEX1': DELETE
    **
    **
    CAUTION: Executing this example will modify the database records!
    ************************************************************************
    DEFINE DATA LOCAL
    1 EMPLOY-VIEW VIEW OF EMPLOYEES
      2 NAME
    END-DEFINE
    *
    FIND EMPLOY-VIEW WITH NAME = 'ALDEN'
      /*
      DELETE
      END TRANSACTION
      /*
      AT END OF DATA
        WRITE NOTITLE *NUMBER 'RECORDS DELETED'
      END-ENDDATA
    END-FIND
    END

### Example 2

If no records are found in the `VEHICLES` file for the person named ALDEN, the `EMPLOYEE` record for ALDEN is deleted.

    ** Example 'DELEX2': DELETE
    **
    **
    CAUTION: Executing this example will modify the database records!
    ************************************************************************
    DEFINE DATA LOCAL
    1 EMPLOY-VIEW VIEW OF EMPLOYEES
      2 PERSONNEL-ID
      2 NAME
    1 VEHIC-VIEW VIEW OF VEHICLES
      2 PERSONNEL-ID
    END-DEFINE
    *
    EMPL. FIND EMPLOY-VIEW WITH NAME = 'ALDEN'
      /*
     VEHC. FIND VEHIC-VIEW WITH PERSONNEL-ID = PERSONNEL-ID (EMPL.)
        IF NO RECORDS FOUND
          /*
          DELETE (EMPL.)
          /*
          END TRANSACTION
        END-NOREC
      END-FIND
      /*
    END-FIND
    END
