SQCloudVMBindParameterIndex
int SQCloudVMBindParameterIndex (SQCloudVM *vm, const char *name);
Description
Return the index of an SQL parameter given its name. The index value returned is suitable for use as the second parameter to SQCloudVMBind. A zero is returned if no matching parameter is found.
This function resembles the bind_parameter_index SQLite API.
Parameters
- vm: A valid VM obtained by SQCloudVMCompile.
- name: The SQL parameter name.
Return value
An int
representing the index of the name parameter.
Example
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 ('?param1');", -1, NULL);
// execute the previously compiled statement
SQCLOUD_RESULT_TYPE type = SQCloudVMStep(vm);
// get the parameter index
int index = SQCloudVMBindParameterIndex(vm, "param1");
