int sqlite3_limit(sqlite3*, int id, int newVal);
This interface allows the size of various constructs to be limited on a connection by connection basis. The first parameter is the database connection whose limit is to be set or queried. The second parameter is one of the limit categories that define a class of constructs to be size limited. The third parameter is the new limit for that construct.
If the new limit is a negative number, the limit is unchanged. For each limit category SQLITE_LIMIT_NAME there is a hard upper bound set at compile-time by a C preprocessor macro called SQLITE_MAX_NAME. (The "_LIMIT_" in the name is changed to "_MAX_".) Attempts to increase a limit above its hard upper bound are silently truncated to the hard upper bound.
Regardless of whether or not the limit was changed, the sqlite3_limit() interface returns the prior value of the limit. Hence, to find the current value of a limit without changing it, simply invoke this interface with the third parameter set to -1.
New run-time limit categories may be added in future releases.
