query functions

query(int column, string value, int limit, int cmp);
query(int column, const char* value, int limit, int cmp);

query(string column, const char* value, int limit, int cmp);
query(const char* column, const char* value, int limit, int cmp);

query(string column, string value, int limit, int cmp);
query(const char* column, string value, int limit, int cmp);

        

query(vector<vector<string>> query, int column, string value, int limit, int cmp);
query(vector<vector<string>> query, int column, const char* value, int limit, int cmp);

query(vector<vector<string>> query, string column, const char* value, int limit, int cmp);
query(vector<vector<string>> query, const char* column, const char* value, int limit, int cmp);

query(vector<vector<string>> query, string column, string value, int limit, int cmp);
query(vector<vector<string>> query, const char* column, string value, int limit, int cmp);

//int limit -- returns the specified value, if -1 unlimited
//int cmp -- (default 0) EQUAL = 0   INCLUDE = 1
