![]() You might not always want to transfer all columns. This method simplifies the query, but ensure that the column structures between the two tables match. If you're transferring data from all columns in the source table to the target table, and the column order matches, you can omit column names: INSERT INTO target_table The WHERE clause allows for conditional data transfer.source_table is the table you are selecting data from.target_table is the table you want to insert data into.The general structure for this combined approach is: INSERT INTO target_table (column1, column2. It allows for copying data based on specific conditions, making it a versatile tool in database management. This method provides flexibility in handling potential duplicate entries. In databases like MySQL, if a record with a unique key already exists and you try to insert a duplicate, you can choose to update the existing record instead: INSERT INTO table_name (column1, column2. Conditional Insert Using ON DUPLICATE KEY This is especially useful when you want to copy data from one table to another based on certain conditions. You can also insert data from one table directly into another using a subquery with the SELECT statement: INSERT INTO table_name1 (column1, column2. This method is efficient as it reduces the number of separate queries sent to the database.

In cases where certain columns have default values set, you don't need to provide a value for them. ![]() However, it's generally recommended to specify column names to avoid potential errors and ensure clarity. If you're inserting values into every column of the table in their respective order, you can omit the column names: INSERT INTO table_nameįor the Employees table, this would look like: INSERT INTO Employees To insert a new record into this table, you would use: INSERT INTO Employees (ID, FirstName, LastName) are the values you want to insert into the respective columns.Ĭonsider a table named Employees with columns ID, FirstName, and LastName. are the names of the columns where you want to insert data. table_name is the name of the table where you want to insert the new record.The basic syntax for the INSERT INTO statement is: INSERT INTO table_name (column1, column2, column3. It is a vital component in database management and manipulation. The SQL INSERT INTO statement allows you to add new records into a database table.
