Using SELECT INTO is an easy way to create a new table based on an existing table in the database. Of course, if you want to create a table using all of the columns in the other table, you can use * instead of listing the columns after SELECT. This new table also has fewer rows – only the rows with the category flower. In this example, we are creating a new table florist which has less columns than the table product (the difference is the column category). After WHERE, write the conditions to filter the data (in our example: WHERE category=’flower’). If you would like to select filtered rows from the table, use the WHERE clause. Then, write the keyword FROM with the name of the existing table (in our example: product). Next, use the keyword INTO with the name of the new table you want to create (in our example: florist). We only selected the columns we’re interested in. Notice that there are more columns in the table product. First, write a SELECT clause followed by a list of columns (in our example: id, name, and price) from the existing table (in our example: product). If you would like to create a new table based on the structure and data from another table, you can use the SELECT INTO clause. This syntax is non-standard SQL, but it’s supported by many popular databases. The SELECT INTO StructureĪnother solution is to use SELECT INTO. The number of rows is limited by using a WHERE clause, filtering the records to only retrieve data from the category flower. The new table florist will contain the definition of the columns from the product table ( id, name, category, and price). Then, you can use any SQL clause: WHERE, GROUP BY, HAVING, etc. In this case, we first use the CREATE TABLE clause with the name for new table (in our example: florist), we next write AS and the SELECT query with the names of the columns (in our example: *), and we then write FROM followed by the name of the table from which the data is gathered (in our example: product). Using CREATE TABLE, you can create a new table by copying data from another table. To create a new table from another table, you can use CREATE TABLE AS SELECT. The table florist doesn’t exist in this database. It is important to note that we are creating a new table. These columns come from the table product but only from the category flower. In the database, let’s create a new table named florist which will store the following columns: id, name, and price. Our database has a table named product with data in the following columns: id (primary key), name, category, and price. Azure Data Studio works for both Azure SQL and on-prem SQL Server installations.You would like to create a new table with data copied from another table. Sure enough, it does! You can write out the list of columns in a table in your query editor by dragging the column folder for the table into the query editor window: Azure Data Studio isn’t just for Azure SQLĭon’t let the name fool ya. Stepping through the Peek Definition example made me wonder if one of my favorite lazy hacks from SQL Server Management Studio works in Azure Data Studio. Bonus: Dragging the Columns folder into a query edit works just like in SSMS The example given in a tutorial of peeking at a table’s definition when writing an insert statement is right on. I also hadn’t realized that Azure Data Studio supports Peek Definition functionality natively. ‘Peek definition’ functionality exists, too There are built-in snippets for lots of things – data definition changes like creating indexes or adding columns, data modification tasks like inserting or deleting rows, or management tasks like listing databases or finding space used.īut you might want to create your own snippets, too. This will initialize a drop-down list which you can arrow through: You can create your own snippets You can check the column mappings on the Mappings tab. To access snippets, simply type sql into the query editor itself. Click on the Settings tab and then select Truncate for the Table action setting. I assumed that I’d open the Command Palette to insert a snippet. And I admit that as soon as I skimmed the tutorial and saw there were snippets, I tried to use them the wrong way. I had no idea that Azure Data Studio had built in snippet functionality. The tutorial taught me a couple of things that I’ve not noticed about Azure Data Studio, even though I’ve used it for a couple of years. This Quickstart is solid and is great for someone new to Azure Data Studio.Īt the end of the Quickstart it suggested I try the Tutorial: Use the Transact-SQL editor to create database objects - Azure Data Studio. Today I walked through the Use Azure Data Studio to connect and query Azure SQL database Quickstart.
