Just started using ColdFusion Builder 2 with ColdFusion 9 and saw the RDS viewer ability in it. I thumbed through Forta's WACK book and tried a simple example from it, a basic INSERT using a Derby Embedded database:
INSERT INTO Directors(FirstName,LastName)
VALUES('Ben','Forta')
If you execute that query using the RDS Query Viewer you get an error:
Statement.executeQuery() cannot be used with a query that returns a row count.
Are INSERTs, DELETEs, and UPDATEs not allowed using this tool? I'm probably just spoiled using SQL Server's Management Studio which will let you do anything if you have the rights.
Thanks!
Ya, AFAIK INSERTs, DELETEs, and UPDATEs not allowed

I am trying to use pre aggregations over CLOUD SQL on Google Cloud Platform but the database is denying access and giving error Statement violates GTID consistency.
Any help is appreciated.
Cube.js done pre-aggregation by CREATE TABLE ... SELECT, but you are using MySQL on top of Google SQL with --enforce-gtid-consistency (has limitations).
Since only transactionally safe statements can be logged, there is a limitation to use CREATE TABLE ... SELECT (and some another SQL), because this statement is actually logged as two separate events.
There are two ways how to solve this issue:
1. Use pre-aggregations to an external database. (recommended way).
https://cube.dev/docs/pre-aggregations/#read-only-data-source-pre-aggregations
2. Use not documented flag loadPreAggregationWithoutMetaLock
Attention: This flag is an experimental and can be removed or changed in the feature..
Take a look at the source code
You can pass it directly in the driver constructor. This will produce two SQL statements to pass the limitation:
CREATE TABLE
INSERT INTO
Thanks
Does the Spanner API support DML statements? For example, is the following supported:
UPDATE SET foo="bar" WHERE foo="baz"
Update as pr mid October 2018:
Cloud Spanner now does support INSERT, UPDATE, and DELETE using direct DML:
Blog post about the change:
https://cloud.google.com/blog/products/databases/develop-and-deploy-apps-more-easily-with-cloud-spanner-and-cloud-bigtable-updates
Docs:
https://cloud.google.com/spanner/docs/dml-tasks
Cloud Spanner does not support INSERT/UPDATE/DELETE DML operations, however you can achieve the same effect by using read-write transactions. All mutations to your data must go through the transaction commit method (in either REST or gRPC), which accepts Mutation objects.
In your example, you would
Start a read-write transaction and execute a SQL statement such as: SELECT <key> from MyTable where foo="baz".
Then commit the transaction and include a list of Mutation objects (one for each row you got back from your select) with the update property to set all the values to "bar".
Google Cloud Spanner itself does not support this, but this JDBC Driver https://github.com/olavloite/spanner-jdbc does support it by parsing the supplied SQL and calling the read/write API of Google Cloud Spanner. Have a look at the code in CloudSpannerPreparedStatement to see how it's done. The driver relies on the SQL parsing offered by https://github.com/JSQLParser/JSqlParser.
As of version 0.16 and newer of the abovementioned JDBC driver, full DML-statements operating on multiple rows are supported. You can use the driver in combination with a tool like SQuirreL or DBVisualizer in order to send the statements to Cloud Spanner.
Have a look here for some examples: http://www.googlecloudspanner.com/2018/02/data-manipulation-language-with-google.html
I am working on a SSIS (2012) package that collects data from our till system to staging area and from staging area to CRM 2011 (on-premise | Roll up 11).
In CRM we have contact entity and order entity. These two entity are related via a guid called contactid(PK in contact) and customerid(FK in order).
when i insert new order in to CRM how do I ensure that the guid is created to associate that order to either a new contact or already existing contact?
I'm assuming since you're using SSIS your doing straight SQL inserts? If so, this is not supported. Ideally you'd be using the SDK, and in that case, you can set the GUID manually before actually creating the record, although the Contact Id still has to exist when creating the Order.
So you'll want to grab all of your existing Contacts up front, then determine for each order, if the contact exists or not. If it does, just set the customerId when you create the order and you're all set. If it doesn't, you'll need to create the Contact (potentially assigning it an Id), and then setting the customerId when you create the order.
I would echo what Daryl has said in that SQL inserts are not supported and generally a bad idea. However there is a solution, a company called Kingsway Soft make a SSIS component that allows you to read and write into CRM using the web services. The best part of it is that it is free if you don't want to run it using SQL agent. Even if you do want to schedule it the cost is very small for such an excellent product.
You can download it from here

I have C++ code, and from it I need to access the DB and make a query in table (with name NECE_TABLE, which has 2 columns - IntID and Status).
Here I need to get "status" column value from DB table (NECE_TABLE) using the IntID from C++ code.
Any help will be greatly helpful. Thanks in advance
Your question is very vague, but in summary you need to:
Use an appropriate client library supported by your database to connect to that database using some user credentials with appropriate permissions for SELECTing from your table
Execute a SQL select to fetch the data you want
There's some confusion as to which database you're using.
If you're using Oracle, you can use the OCCI client library to connect to the database and execute SQL statements. See section 2 of the linked document, where it describes connecting to a database and executing SQL queries.
Take a look at this link - it's a simple tutorial on how to get started with MySQL and C++. You say you are using vanilla SQL in your tags, but the two should be compatible as long as you stick to the more basic queries.
I have to migrate some legacy data from stand-alone sql server database to sharepoint list.
I'm going to use programmatic approach and write a code that communicates with sharepoint list asmx web service.
Are there some "data transformation wizards" to simplify such a task or a better approach to port legacy data from sql server database to sharepoint list?
Thank you in advance!
Being one time operation, I would not worrry about Best Practice but would consider what's the fastest way to do it.
You can use Excel 2010 (I have not tested it with Excel 2007) export data to Sharepoint 2010. Here are the high level steps:
Import data from SQL Server using DATA Tab in the ribbon
Excel would automatically create a TABLE
Now you can prepare the data for Export to Sharepoint. Here, you can remove unwanted columns, add new columns remove unwanted rows, arrange columns etc.
While being in the Table, access the "Export Table To Sharepoint List" functionality to publish you data to Sharepoint. More information about this is available at: http://office.microsoft.com/en-gb/excel-help/export-an-excel-table-to-a-sharepoint-list-HA010131472.aspx
It is quick! but let;s be aware of the limitations:
1. It cannot publish data to a list which already exists
2. It will not create a content type for the exported list. The columns are directly attached to the list.
If you want greater control over the migration, programming may be the way to go unless someone has a better idea in this great forum!
