We have several options when it comes to using SQL to clone a table in MariaDB. And we have the option to clone the table with data, or without data.
Here are three SQL options for cloning a table in MariaDB.
how to
Return All DEFAULT Constraints in a SQL Server Database (T-SQL)
In SQL Server, we can query the sys.default_constraints system catalog view to return a list of DEFAULT constraints in the current database.
How to Create a Sequence in SQL Server
SQL Server supports sequences. Sequences enable us to create our own sequence of numeric values.
Sequences are similar to identity columns in that they generate a unique value that can be used to identify a column. However, sequences are created completely independently of any table.
List All Synonyms in a SQL Server Database (T-SQL)
In SQL Server, we can use the sys.synonyms system catalog view to get a list of synonyms in the current database. This view returns all objects in the sys.objects view of type SN (which stands for synonym).
Fix “ERR value is not an integer or out of range” When using the HRANDFIELD Command in Redis
If you’re getting an error that reads “ERR value is not an integer or out of range” when using the HRANDFIELD command in Redis, it could be because you’re passing a second argument that isn’t an integer. Or if it is an integer, it could be out of range.
Return All CHECK Constraints in a SQL Server Database (T-SQL)
In SQL Server, we can query the sys.check_constraints system catalog view to return a list of CHECK constraints in the current database.
Fix “ERR wrong number of arguments for ‘srem’ command” in Redis
If you’re getting an error that reads “ERR wrong number of arguments for ‘srem’ command” in Redis, it’s probably because you’re calling the SREM command with the wrong number of arguments.
To fix this issue, make sure you pass the correct number of arguments. At the time of writing, the SREM command requires at least two arguments.
Return the Definition of All Computed Columns in a SQL Server Database (T-SQL)
In SQL Server we can run a query against the sys.computed_columns system catalog view to return all computed columns and their definitions.
How to Insert Multiple Rows in SQL
When working with SQL, we can use the INSERT statement to insert a new row into a table. But what if we want to insert more than one row?
Fortunately, we can still use the INSERT statement. Below is a quick example that inserts multiple rows using SQL.
