MSCEWI2073

Bash variables found, using SnowSQL with variable substitution enabled is required to run this script

This is a deprecated version of the SnowConvert documentation, please visit the official site HERE.

Severity

Low

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:

.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:

EXECUTE IMMEDIATE
$$
