By default, the SQLite command line shell formats query output as a pipe-separated list, without column headers.
If you need to output the results using commas instead of the pipe-symbol, you can specify this with the .separator dot command.
If you need to format your results as string literals, see How to Enclose Strings in Single Quotes. Or if you need any strings to be enclosed in double quotes, see How to Format Results as CSV.
Continue readingBy default, when you connect to the SQLite command line shell and run a query, the result is returned as a pipe separated list.
You might have noticed that the results don’t include the column names, which can make your results confusing if you’re trying to read them, especially if the query returned many columns.
Fortunately, there’s an easy way to format the output so that it’s displayed as a column with column headers.
Continue readingSQLite provides us with the ability to run scripts directly from a file. This can be especially useful when you have a large script (such as creating a bunch of database tables and inserting data into those tables).
Below are five ways to run SQL scripts directly from a file in SQLite.
Continue readingIn SQL Server, you can use GOTO to alter the flow of execution. You can use it to “jump” to another part in the T-SQL code.
The way it works is, you create a label, then you can use GOTO to jump to that label. Any code between GOTO and the label are skipped, and processing continues at the label.
GOTO statements and labels can be used anywhere within a procedure, batch, or statement block. They can also be nested.
In SQL Server, you can use any of the following five ways to return a list of temporary tables using Transact-SQL.
These return both local and global temporary tables.
Here’s some T-SQL code you can use to get a list of all CHECK and foreign key constraints in a SQL Server database.
The RAND() function in SQL Server returns a pseudo-random float value from 0 through 1, exclusive.
This function can be deterministic or nondeterministic, depending on how it’s invoked.
Continue readingIn SQL Server, you can encrypt a view at the time you first create it, or you can alter it later to include encryption.
To create a view with T-SQL, you use the CREATE VIEW syntax. To encrypt it, you add the WITH ENCRYPTION argument.
You can also use the same argument to encrypt an existing view when using ALTER VIEW.
In SQL Server, temporary tables are created using the same CREATE TABLE syntax as regular tables. The difference is that temporary tables’ names are prefixed with either one or two number signs (#), depending on whether it’s a local temporary table or global temporary table:
#)##)In SQL Server, you can encrypt a stored procedure at the time you create it, or you can alter it later to include encryption.
To create a stored procedure with T-SQL, you use the CREATE PROCEDURE syntax. To encrypt it, you add the WITH ENCRYPTION argument.
You can also use the same argument to encrypt an existing procedure when using ALTER PROCEDURE.
