Troubleshooting
Problem
Google BigQuery has a single character data type called STRING, which is a varying length character data type. By default the Google JDBC driver will describe the precision (size) of any STRING column as 65K.
Potentially, a model or report expression may be computed to have a precision greater than 65K, resulting in an error from Dynamic Query.
Typically character data values may have a maximum length which is much smaller, such as 1024 or less.
Symptom
Default precision in metadata returned by the Google BigQuery JDBC driver is too large and should be reduced.
