DESCRIPTION

     These constants define various performance limits that can be lowered at
     run-time using sqlite3_limit().  The synopsis of the meanings of the var-
     ious limits is shown below.  Additional information is available at Lim-
     its in SQLite.

     SQLITE_LIMIT_LENGTH
             The maximum size of any string or BLOB or table row, in bytes.

     SQLITE_LIMIT_SQL_LENGTH
             The maximum length of an SQL statement, in bytes.

     SQLITE_LIMIT_COLUMN
             The maximum number of columns in a table definition or in the
             result set of a SELECT or the maximum number of columns in an
             index or in an ORDER BY or GROUP BY clause.

     SQLITE_LIMIT_EXPR_DEPTH
             The maximum depth of the parse tree on any expression.

     SQLITE_LIMIT_COMPOUND_SELECT
             The maximum number of terms in a compound SELECT statement.

     SQLITE_LIMIT_VDBE_OP
             The maximum number of instructions in a virtual machine program
             used to implement an SQL statement.  If sqlite3_prepare_v2() or
             the equivalent tries to allocate space for more than this many
             opcodes in a single prepared statement, an SQLITE_NOMEM error is
             returned.

     SQLITE_LIMIT_FUNCTION_ARG
             The maximum number of arguments on a function.

     SQLITE_LIMIT_ATTACHED
             The maximum number of attached databases.

     SQLITE_LIMIT_LIKE_PATTERN_LENGTH
             The maximum length of the pattern argument to the LIKE or GLOB
             operators.

     SQLITE_LIMIT_VARIABLE_NUMBER
             The maximum index number of any parameter in an SQL statement.

     SQLITE_LIMIT_TRIGGER_DEPTH
             The maximum depth of recursion for triggers.

     SQLITE_LIMIT_WORKER_THREADS
             The maximum number of auxiliary worker threads that a single pre-
             pared statement may start.
