Label



Required. The name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.

Schema name


The database schema name. In case it is not defined, then the suggestion for the Table Name will retrieve all tables names of all schemas. The property is suggestible and will retrieve available database schemas during suggest values.

Note

The values can be passed using the pipeline parameters but not the upstream parameter.

Example: SYS
Default value:  [None]


Table name

Required. The table name to execute the delete on.

Note

The values can be passed using the pipeline parameters but not the upstream parameter.


Example: people
Default value:  [None]
 

Delete  Condition (Truncates Table if empty)

This is an expression property to specify the SQL WHERE clause of the delete statement. The delete condition may also be passed via an upstream Snap or through the pipeline parameters.

Note

Specify a valid WHERE clause for the delete condition. If you leave this field blank, the Snap truncates the table.


Examples: 

Without using expressions

Using expressions

  • "EMPNO=$EMPNO and ENAME=$EMPNAME"

  • email = $email 

  • emp=$emp

  • "emp='" + $emp + "'"

  • "EMPNO=" + $EMPNO + " and ENAME='" + $EMPNAME+ "'"


Warning
titleCaution

Using expressions that join strings together to create SQL queries or conditions has a potential SQL injection risk and is hence unsafe. Ensure that you understand all implications and risks involved before using concatenation of strings with '=' Expression enabled.

Example

In this pipeline, we delete an entire table 'Disney' from the 'Snaplogic' schema. 

Note

Give the delete conditions if a certain record or a column is to be deleted. You may also use the MySQL Select Snap to select a name of the record, and then give the delete condition in the MySQL Delete Snap to delete only those particular values from the table that satisfy the delete condition.
