When I use the Cashier table or some other tables that have small amounts of records the process proceeds and table is inserted into the external database. But when I change the cashier into the transaction database (400k+ records), Visual Studio reports an error near "Transaction" Help would be appreciated thanks.
Cashier Database (working)
Dim query As String = "select * into MyDatabase2.dbo.Cashier from bos_primary_db.dbo.Cashier"
Transaction Database (not working)
Dim query As String = "select * into MyDatabase2.dbo.Transaction from bos_primary_db.dbo.Transaction"
This is the error message:
Incorrect syntax near the keyword 'Transaction'
this is probably because Transaction is a reserved word in SQL.
Depending on your RDBMS (that you didn't specify), there are ways to "escape" it:
for Sql Server, you should wrap reserved words in square brackets:
select * into MyDatabase2.dbo.[Transaction] from bos_primary_db.dbo.[Transaction]
For MySql you should use an apostrophe:
select * into MyDatabase2.dbo.`Transaction` from bos_primary_db.dbo.`Transaction`
For Oracle you should use double quotes:
select * into MyDatabase2.dbo."Transaction" from bos_primary_db.dbo."Transaction"
Note: You should always try to avoid using reserved words. This link describes my favorite way of do it.

I have to create a list box control that contains all of the queries except for the system queries. Recall that system query names begin with the ~ character.
When I try to write SQL code in the row source (in the property sheet) for my frmQueries form I keep getting an error saying:
Syntax error (missing operator) in query expression:'[Type]=5 And Left([Name],1)<>"~" OORDER BY [Name]'
The code I entered is:
SELECT [Name] FROM MYSysObjects
WHERE [Type]=5 And Left([Name],1)<>"~"
OORDER BY [Name];
I am not sure why I am getting this error or how I can fix it.
OORDER should be ORDER, MYSysObjects should (presumably) be MSysObjects, and you can also replace Left([Name],1)<>"~" with [Name] not like "~*" (assuming MS Access instead of SQL Server).

How can I comment special \ commands in PostgreSQL's psql commandline tool?
(5 answers)
Closed 8 years ago.
I have a query in an excel file that I inherited from the previous user/creator of the tool. The external connection is to a PostgreSQL database. Here's the line of script that I need to decipher so that I can hopefully adjust the date range for the query:
with
icon_date as (select max(icon.date::date)/* '1/1/2014'::date*/ as icon_date from pmm.icon)
...
pmm is the schema and .icon is the table name
My specific question is what this part means:
/* '1/1/2014'::date*/
I have no clue what surrounding a date::data type with /* */ would do in the first part of the query. Any ideas? I can post more of query if that would help.
That is just a comment and it will be ignored.
There are (at least) two ways to put comments into SQL:
everything after -- until end of line
everything between /* and */ (even spanning lines)
My guess is that this is code left over from testing, where instead of the max you would select some fixed date (because it is faster, or data was missing).

How can prepared statements protect from SQL injection attacks?
(10 answers)
Closed 8 years ago.
I heard that separated SQL clause and args can protect against SQL injection. For example,
clause = SELECT * WHERE ID = ? AND NAME = ?
with ID = 23, and NAME = "Tom".
Can someone explain to me how it works?
Basically, you're making the distinction between data and the actual code (query part) very clear. You're telling the SQL server: this is clearly data and this is clearly code.
This way, you're basically skipping the part where the server has to pull apart the code and data from your query so there's no chance the server can misinterpret bits of data as part of your query.
Edit: as per the link in the comments, this answer pretty much answers your question much better than I've explained here.

I use the AdventureWorks practice database attached to SQL Server 2012.
A simple statement like:
SELECT * FROM HumanResources.Shift;
gives me this error:
Msg 208, Level 16, State 1, Line 1
Invalid object name 'AdventureWorks2012'.
I also tried:
USE master
GO
SELECT * FROM HumanResources.Shift;
Received same error message. Any idea to why this is happening?
Is AdventureWorks2012 the name of a database or a table?
USE <database name>
means use the specified database to run the query against.
SELECT * FROM <table name>
means select all the rows from the specified table.
--Edit because of change in question--
You don't want to use Master, you want to use the name of your DB. Next, using the object explorer, I would make sure the table actually exists in the Database you created.

New to views with sql server, not sure how to view the information it has gathered with vbscript. I know it is not as simple as:
select * from EXAMPLE_VIEW
I want to get the information from my example view loop through it and display it, however when i try to do that sql query i get invalid object name.
My question is how do you sql query a view
You should probably be doing this:
SELECT column1, column2 FROM dbo.EXAMPLE_VIEW;
This is because if your user has a different default schema than dbo, it might be checking for some other view with the same name under a different schema. (You also know not to use SELECT *, right?)
So you should also make sure your user account has select permissions on the view and/or the table(s) behind it.
Bad habits to kick : using SELECT * / omitting the column list
Bad habits to kick : avoiding the schema prefix
select * from EXAMPLE_VIEW
...is the correct way to query a SQL Server view.
If it's not working for you, you have a different kind of problem: maybe no permissions, maybe no server connection, maybe a view called EXAMPLE_VIEW doesn't exist, maybe something else.
Whatever it is - we need the exact error message and as much example code as possible to help you.
But the SQL itself is correct.
Is your current database set correctly after establishing connection? It can be set using connnection string (http://www.connectionstrings.com/) or by specyfying it witin query itself:
SELECT * FROM MYDB.dbo.EXAMPLE_VIEW;
