If I understand your question, the answer is NO. There is NO function
like sqlite3_insert_data_into_table(TableName, Data, FieldName). The
SQL engine responsible for reading and writing data from and to tables
only responds to SQL queries passed to it via functions like sqlite3_exec().
For
, the particular function will enter the record of values into that
table.
Is there any C API like that in SQlite.

Bhaskar

Because some people do want to store strings with embedded NULs, for various
