Issue/Introduction

Trying to obfuscate data on snowflake DB and when we are trying to execute the obfuscation scripts, getting below error message in Logs 

2021-08-31 12:55:20.116 Table masking without primary key or unique index is not supported for Snowflake databases due to limitation in the driver.
2021-08-31 12:55:20.116 exit value = 1
2021-08-31 12:55:20.116 Sleeping for 500 milliseconds before exiting

Environment

Release : 4.9

Component : Fast Data Masker

Cause

It is a limitation at driver level with current design implementation of FDM.

If the tables you are trying to mask doesn't have any primary key or unique index, then FDM cannot mask columns in those table. 

Resolution

 

The error message really means what it says.

If the tables you are trying to mask doesn't have any primary key or unique index, then FDM cannot mask columns in those table.

Add some unique value column to this table to be able to mask it.
