Question

i have the following code.My table is called ‘tableu’.I want replace ‘tableu’ with a variable that will hold the table name. How can i represent that.

   query.prepare(
                "INSERT INTO tableu (village, weight, diet, age)"
                "VALUES (:village, :weight, :diet, :age)"
                );

Answer 1

If you want to change your table name from tableu to lets say NewTableName, it can be done using any of the following syntax:

query.prepare(
              "RENAME tableu TO NewTableName"
             );

OR

query.prepare(
              "ALTER TABLE tableu RENAME TO NewTableName"
             );

Update:

May be the OP is looking for this.

QString tableName = QString("tableu");
QString sqlQuery = QString("INSERT INTO %1 (village, weight, diet, age) VALUES (:village, :weight, :diet, :age)").arg(tableName);
