Function ejdb_sys::ejdbqryexecute

pub unsafe extern "C" fn ejdbqryexecute(
    jcoll: *mut EJCOLL, 
    q: *const EJQ,

) -> EJQRESULT

Execute the query against EJDB collection. It is better to execute update queries with specified JBQRYCOUNT control flag avoid unnecessarily rows fetching.

@param jcoll EJDB database @param q Query handle created with ejdbcreatequery() @param count Output count pointer. Result set size will be stored into it. @param qflags Execution flag. * JBQRYCOUNT The only count of matching records will be computed without resultset, this operation is analog of count(*) in SQL and can be faster than operations with resultsets. @param log Optional extended string to collect debug information during query execution, can be NULL. @return TCLIST with matched bson records data. If (qflags & JBQRYCOUNT) then NULL will be returned and only count reported.
