If you are using gviz, use the LIKE operator
like- A text search that supports two wildcards: %, which matches zero or more characters of any kind, and _ (underscore), which matches any one character. This is similar to the SQL LIKE operator. Example:where name like fre%matches 'fre', 'fred', and 'freddy'. (Ensure you use the UriEncode block to properly encode the%)
or use starts with
SELECT * WHERE B STARTS WITH ''01'
