This was a prerequisite to move to smarter stuff вЂ“ like database theory, and more importantly, returning results from our database. WeвЂ™ve used it to populate tables created in the previous article. In this article, weвЂ™ve covered one of the four most important SQL statements вЂ“INSERT INTO TABLE statement.

WeвЂ™ll use a similar approach later when we are running multiple UPDATE and DELETE statements (and even when creating SELECT statements).

=' INSERT INTO city ( city_name, lat, long, country_id ) VALUES ( '' & B2 & '', ' & C2 & ', ' & D2 & ', ' & E2 & ' ) 'ДЇeel free to use these formulas to automate your tasks. The formula used to insert the first country (Germany) is: Note: Personally, in the context of databases, I find Excel very useful when I need to create multiple statements and when presenting results and/or creating dashboards. In such situations, I prefer using Excel and formulas. There is no point in typing these statements manually, but you should rather go with a smarter approach вЂ“ prepare formulas (or a script) that will automate this part. This stands not only for the INSERT INTO TABLE statement but also for UPDATE and DELETE statements. In many cases, youвЂ™ll need to run multiple SQL statements based on the dataset provided to you. We can conclude that both tables in our database contain data and now weвЂ™re ready to вЂњplayвЂќ with something way cooler than this.

Please notice that after executing queries now we have Results and Messages sections under queries: The result is shown in the picture below.

In order to check the contents of these two tables, weвЂ™ll use two simple SELECT statements: They are also related to each other, but weвЂ™ll talk about that in the following article: You can see that we have one table where weвЂ™ll store data related to countries and another one for data related to cities. This is the model we have created in the previous article. WHERE condition INSERT INTO TABLE exampleД«efore doing anything, letвЂ™s check what is stored in our tables. INSERT INTO destination_table (column_list, вЂ¦)

The simplified syntax for one such case where INSERT and SELECT statements are combined is given below: Note: The INSERT INTO TABLE statement could be written in such manner we insert multiple rows with 1 statement or even combined with the SELECT statement. I personally prefer listing all column names, because this approach would work even if we add new columns to the existing table. INSERT INTO table_name VALUES (column_values) In case youвЂ™re inserting all values in the table, you donвЂ™t need to list all columns after the table_name and you could use even more simplified syntax: Notice that column values should match column types definition (e.g., you canвЂ™t insert a textual value into the numerical column/attribute). In such INSERT INTO statement, youвЂ™ll need to define the table_name where youвЂ™re inserting data into, list all columns (maybe youвЂ™ll use all of them, but maybe only a few of them), and then list all values. INSERT INTO table_name (column_list) VALUES (column_values) In this article weвЂ™ll use simplified, but also most common syntax: Please take a look at the T-SQL INSERT INTO TABLE complete syntax here. It is one of the four important SQL DML (Data Manipulation Language) statements SELECT вЂ¦ FROM, INSERT INTO TABLE, UPDATE вЂ¦ SET, and DELETE FROMвЂ¦ The complete syntax is pretty complex since the INSERT INTO could also be a very complex statement. The INSERT INTO TABLE statement is the one weвЂ™ll use to solve this problem. There is no point in creating database structures and not having any data in the database. WeвЂ™ll also check the contents of both tables before and after these commands using the SELECT statement. In order to do so, weвЂ™ll prepare statements in Excel and then paste these statements into SQL Server and execute them. In the previous article, weвЂ™ve created two tables, and now weвЂ™re ready to use the SQL INSERT INTO TABLE command and populate these tables with data.
