SQCloudVM *SQCloudVMCompile (SQCloudConnection *connection, const char *sql, int32_t len, const char **tail);


Compile an SQL statement into a byte-code virtual machine. This function resembles the sqlite3_prepare SQLite API.


  • connection: A valid connection object obtained by SQCloudConnect or SQCloudConnectWithString
  • sql: The statement to be compiled.
  • len: If the len argument is negative, then sql is read up to the first zero terminator. If len is positive, then it is the number of bytes read from sql.
  • tail: If the tail argument is not NULL then *tail is made to point to the first byte past the end of the first SQL statement in sql. SQCloudVMCompile compiles only the first statement in sql, so *tail is left pointing to what remains uncompiled.

Return value

An SQCloudVM opaque datatype representing the compiled statement.


int main (int argc, const char * argv[]) {
    // setup config
    SQCloudConfig config = {0};
    config.username = "myusername";
    config.password = "mypassword"

    SQCloudConnection *conn = SQCloudConnect("myproject.sqlite.cloud", SQCLOUD_DEFAULT_PORT, &config);
    if (SQCloudIsError(conn)) {
        printf("ERROR connecting: %s (%d)\n", SQCloudErrorMsg(conn), SQCloudErrorCode(conn));
        return -1;
    } else {
        printf("Connection to host OK...\n\n");

    // choose a database first
    SQCloudResult *r = SQCloudExec(conn, "USE DATABASE mydatabase.sqlite;");

    // compile the INSERT SQL statement
    SQCloudVM *vm = SQCloudVMCompile(conn, "INSERT INTO table1 (col1) VALUES (?1);", -1, NULL);

    // do something with vm
