Create database table with current date as tablename - sql-server

Question

I want to create a database table with current date as tablename using sql query

Answer 1

In SQL Server you can name a table basically anything you want by enclosing it in [].
So generate dynamic sql and execute it:
EXEC sp_executesql N'create table [12/10/2014] (ab varchar(10));'
Further you can get the whole thing dynamically:
DECLARE #sql NVARCHAR(MAX) = 'create table [' + CONVERT(nvarchar(30), GETDATE(), 101) + '] (ab varchar(10))'
EXEC sp_executesql #sql
EDIT: This was originally tagged as MySQL so here is the solution for that as well, because I was curious.
SELECT DATE_FORMAT(CURDATE(), '%m/%d/%Y');
SET #SQL =CONCAT('CREATE TABLE `' ,DATE_FORMAT(CURDATE(), '%m/%d/%Y'), '` (id int(10))');
PREPARE stmt FROM #SQL;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

Though I think it's not a good option, You can get the current date from C# using
DateTime.Today
It can look like
using (SqlConnection con = new SqlConnection(conStr))
{
try
{
con.Open();
using (SqlCommand command = new SqlCommand("CREATE TABLE " + "someNamingPrefixHere_" + DateTime.Today + " (ab varchar(10));", con))
command.ExecuteNonQuery();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

Answer 3

first:
do you really need to create a table that has a name as current date? why not create only a table and add a field that is a date and keep adding your data filling the date field with the current date?
if you really need to create many tables then:
you can't have a table name with the "/" character, you will have to replace those with something that is accepted by MySQL or SQLServer.
anyway to get the current date in c# use the DateTime.Now Property in c# and then you can format it using the DateTime.ToString Method (String) passing the format you wish to use like:
string tableName = DateTime.Now.ToString("ddMMyyyy");
this will give you a result like "29102014" if it's 29th october 2014.
then you can create the sql statement using the sql syntax from MySQL or SQLServer, open a connection, execute the command and then close the connection.

You should seriously learn about some SQL design practices. One file should be a row, but one day shouldn't be a whole table. I can't provide any specific answer with this description of your "problem", but easiest way would be just add another column "date" and that's it. Finished work. It's insane to have a table for each day.

Answer 5

This is how I obtained a table name with date and time like MY_TABLE_2019-03-25_08h45m32s687 in MS SQL server:
DECLARE #MIGRATION_TABLE_1 VARCHAR(100);
SET #MIGRATION_TABLE_1= convert(varchar(25), getdate(),121);
SET #MIGRATION_TABLE_1=REPLACE(#MIGRATION_TABLE_1,' ','_');
SET #MIGRATION_TABLE_1=STUFF(#MIGRATION_TABLE_1,14,1,'h')
SET #MIGRATION_TABLE_1=STUFF(#MIGRATION_TABLE_1,17,1,'m')
SET #MIGRATION_TABLE_1=STUFF(#MIGRATION_TABLE_1,20,1,'s')
SET #MIGRATION_TABLE_1='MY_TABLE_'+#MIGRATION_TABLE_1;
The STUFF function calls are for replacing the , : and . in the default date format
2019-03-25 08:45:32.687 to
2019-03-25_08h45m32s687
At this stage, you can display the content of the variable #MIGRATION_TABLE_1 with
SELECT #MIGRATION_TABLE_1 AS VARCHAR;
Then, you have to use the variable name into an EXEC statement as everything has to be dynamic, for example :
EXEC('CREATE TABLE ' + #tablename + ' REST OF YOUR ARGUMENTS);
