SQL

Syndicate content 29 

I am experiencing a problem with an EDI process that uses a SQL Batch Service to connect to our DEV environment.  However, when we point the EDI service to our TEST server, it errors out.

I have checked every single property on our TEST and DEV servers as well as the properties on the associated tables.  They are identical.  Nothing has changed in the SQL either.

Hi, we are a veterinary lab and we use both the LAB and FIN systems of Antrim. Now we are looking to expose the data in a SQL/Object compatible way so we were wondering if same / similar things had been done by other community members already? If so, could you please share your approach / experience / gotchas with us and we are all ears. I can be reached at yang.jiao@antechmail.com . Thank you!

Hi All, I am a Data Architect and am trying a method of deploying alter statements onto Cache DB.

My Data Modeling tool generates alters as this.. So question is if the Cache has a way to rename table? If so what is it?

ALTER TABLE <SchemaName>.GROUP_TYPE_NODES RENAME TO GROUP_TYPE_10082019140110000
;

This is giving error.

HI

We have a local running WINDOWS MySql, which we connect to via MySQL Workbench  :::Mysql@localhost:3306

We have java :: C:\Program Files\Java\jdk1.8.0_221\bin

 

How do we create a DSN that we can use in the business service settings to connect and run our query?

Do we make a ODBC or JDBC DSN.

What settings for either

Hi,

I've a Service utilising the Adapter EnsLib.SQL.InboundAdapter, which uses a Credentials item set with the details of a local SQL account. This currently works, however, we're looking to use the credentials of an AD domain account.

The domain account is a member of an AD security group, which has the required permissions on the source SQL database. I've checked that access is possible with this account via SQL studio.

I have several BPL's that act like SQL Server Integration Services (SSIS) where they are transferring data. When I do this they are all being written under 1 session id, is it possible to make the BPL create multiple session ID's as it is cycling through a Snapshot, so it is easier to read in the trace?

Thanks

Date range queries going too slow for you?  SQL Performance got you down?  I have one weird trick that might just help you out! (SQL Developers hate this!)*

If you have a class that records timestamps when the data is added, then that data will be in sequence with your IDKEY values - that is, TimeStamp< TimeStampif and only if ID1 < IDfor all IDs and TimeStamp values in table - then you can use this knowledge to increase performance for queries against TimeStamp ranges.  Consider the following table:

hi,

i have two where-clauses:

a)  ... WHERE company=1 and product=7

b)  ... WHERE product=7 and company=1 

with other words the position of the where fields are swapped.

now the question is:

bring the where clauses a) and b) the same performance(queryplan) or do i have to write it in a special order???

in my point of view, there is a  parser/optimizer who cares about this, so i don't have to care about.

Hello,

I have a small SQL question.  

Running an example queries in our Samples Namespace: 

1. select top 5 Description,Category from Cinema.Film order by Category - runs fine no issues and returns 2 columns as expected

2. select top 5 * from Cinema.Film order by Category - runs fine no issues and returns 8 columns as expected

3. select top 5 Description,Category,* from Cinema.Film order by ID - runs fine no issues, and returns 10 columns, with my first 2 repeated

4. When I try to combine the first 2 queries:

Hi, I have used CSP to exec SQL selects from  any own NAMESPACE. But in our servers we have many SQL GATEWAY CONNECTIONS.

I'd like to create a CSP page that could use these gateway to exec SQL using these gateway connections, only Administrators will use that page to launch many select at many dsn. I'm not sure if we must deploy that CSP on %SYS namespace and how to use DSN(SQL Gateway connections) that are defined on server.

Anoyone has made that?

For example:

DSN CLIENT ONE

DSN CLIENT ONE

 

CSP Webpage:

TEXTBOX: Introduce your select:

Our team is reworking an application to use REST services that use the same database as our current ZEN application. One of the new REST endpoints uses a query that ran very slowly when first implemented. After some analysis, we found that an index on one of the fields in the table greatly improved performance (a query that took 35 seconds was now taking a fraction of a second).

The newer dynamic SQL classes (%SQL.Statement and %StatementResult) perform better than %ResultSet, but I did not adopt them for some time because I had learned how to use %ResultSet. Finally, I made a cheat sheet, which I find useful when writing new code or rewriting old code. I thought other people might find it useful.

First, here is a somewhat more verbose adaptation of my cheat sheet:

I've setup ODBC connection so I can access Cache data within SQL Server.

I want to be able to write SQL queries for internal monitoring purposes, similar to what's possible with SQL Server.  Specifically I want to be able to check mirroring status (i.e. check which is the current primary mirror member), check the status of any Ensemble productions (started/stopped), check the status of business hosts etc.  I want to do all of this from SQL Server to go with our other system monitoring solutions.

Hello community! I have to work with queries using all kinds of methods like embedded sql and class queries. But my favorite is dynamic sql, simply because of how easy it is to manipulate them at runtime. The downside to writing a lot of these is the maintenance of the code and interacting with the output in a meaningful way.

I'm having trouble accessing the snapshots  EnsLib.SQL.Snapshot in %Library.ListOfObjects that are returned from method ExecuteProcedure in EnsLib.SQL.OutboundAdapter.  The Microsoft SQL stored procedure I am executing returns multiple resultsets.

The issue I am having is that my code works fine when executed in the business operation (commented out in the code below) but when it is executed in the business process it errors.  Any ideas as to why this happens?  The error I get is:
