# Run SQL query against all MySQL tables in all databases via mysql.sh
|
|
#
|
|
# Query can contain {db} and {table} placeholders which will be replaced for each table
|
|
#
|
|
# FILTER environment variable will restrict to matching fully qualified tables (<db>.<table>)
|
|
#
|
|
# Auto-skips information_schema, performance_schema, sys and mysql databases for safety
|
|
#
|
|
# Tested on MySQL 8.0.15
