Alternative for LIKE syntax

Hello, I am trying to use the LIKE ‘a%’ sign to create a chart that only shows certain data that begins with the first few letters. It is correct SQL syntax just doesn’t seem to work in Grafana. Can anyone help with an alternative. Below Is query. I want to replace ‘ARCHDB501’ with anything that starts with ‘ARCHDB%’

SELECT count(“value”) FROM “autogen”.“MailBox_Size” WHERE (“MailBox_DataBaseName” = ‘ARCHDB501’) AND $timeFilter

Thank you

Create a variable and use in command in sql instead of like operator
