Important Notice: Migration of Documentation Website

Please be advised that our documentation website is currently undergoing a migration to a new platform. To ensure you have access to the most up-to-date information, we kindly request that you visit our new documentation website located at:

Official Snowflake Snowconvert Documentation

Thank you for your understanding.

Description

When the source code of a script file migrated to Snowflake Scripting contains Bash variables placeholders ($variable or ${variable}), SnowConvert transforms them into SnowSQL variables (&variable or &{variable}).

This warning is generated to point out that the execution of the migrated script now depends on SnowSQL to work, please consider the following when running the script in SnowSQL:

• Variable substitution must be enabled.

• All variables must be defined.

• Run the file as a batch script.

Example Code

Input Code:

IN -> Teradata_01.bteq

.LOGON dbc, dbc;

select '$variable', '${variable}', '${variable}_concatenated';

select $colname from $tablename where info = $id;

select ${colname} from ${tablename} where info = ${id};

.LOGOFF;

Output Code:

OUT -> Teradata_01.sql

-- Additional Params: -q snowscript
