{{smcfunc |function=db_query |usage=$smcFunc['db_query'] (identifier, query, values, connection) |description=Works Similar to how db_query worked in 1.x versions. |parameters={{parmdesc
|identifier|d1=is used to identify specific query types in which it is necessary to replace portions of the query for compatability across all Database Management Systems supported by SMF. The query must be written for MYSQL. The db_query function will alter the query.{{parmdesc
|substring|d1=for the SQLite database, SUBSTRING will be replaced by SUBSTR
|See the function smf_db_query|d2= in Subs-DB-{dbms}.php for the full list of replacements.
}}
|values|d2=is an array of values you are intending to use in the query.
