Conversion failed when converting the varchar value 'xxxx' Microstartegy

Error "Conversion failed

Error "Conversion failed when converting the varchar value 'xxxx' to data type int" happens when displaying Picture type attribute form using ApplySimple in expression against SQL Server 2012 in MicroStrategy

The attribute form is in Picture type and defined with the following ApplySimple function with Int type column [ID_BARANG] as the input parameter against SQL Server 2012.

Solutions is to use Concat("Images/demo/s", [BARANG_ID_INT], ".png")

ApplySimple("'images/demo/'&#0&'.png'", [ID_BARANG])

However, when running reports with attribute to show the picture form in Web, error message happens in both Web and Developer.

Conversion failed when converting the varchar value 'images/demo/s' to data type int.

STEPS TO REPRODUCE:

SQL Server 2012 database should be used as the warehouse.

Create an attribute form as type Picture and us custom expression as below where column [ID_BARANG] is of type Int in the database.

1. ApplySimple("'images/demo/'&#0&'.png'", [ID_BARANG])
2. Create report with the attribute and show the Picture form.
3. Run report in Web and Developer. Error message will occur.

CAUSE:

The syntax used in ApplySimple is incorrect for SQL Server 2012 database.

ACTION:

Use Concat function instead.

Concat("Images/demo/s", [BARANG_ID_INT], ".png")

NOTE: This is database specific issue. Using the same expression against Microsoft Access database would not result in any error.

Reduce Intelligent Cube Size By Finding Intelligent Cube Objects Which Are Not In Use

Reduce Intelligent Cube Size By Finding Intelligent Cube Objects Which Are Not In Use If the i-cubes can potentially be reduced in size an audit can be performed on the cube objects to see which cube objects are not being used by any of the view reports, documents, or dossiers. The below are examples for a few of the common metadata database platforms . NOTE: To perform this audit, queries are run against the MicroStrategy metadata database. Ensure a metadata backup is taken prior to performing the below actions. Steps: 1) Identify the object ID of the Intelligent cube to be audited by checking the objects Property window 2) Identify the object ID of the project this cube exists within by opening the Project Configuration Sample Cube ID = CFAF1E9B4D53990698C42E87C7AF2EB5 Sample Project ID = B7CA92F04B9FAE8D941C3E9B7E0CD754 3) Run the below SQL against the metadata database by replacing the Cube ID and Project ID within the respective ...

Algorithm to calculate Logical Table Size in Microstrategy

How are the fact tables determined using the logical table size for SQL generation in MicroStrategy The logical table size is an integer number that represents the granularity or level of aggregation of a particular table. It is called 'logical' because it is not related to the physical size of the tables (number of rows). It is calculated according to the attribute IDs that are present in the table and their level in the system hierarchy. Even though, the number does not reveal the actual number of rows in the table, it is an accurate way of measuring a table size without having to access its contents. IMPORTANT: The system hierarchy is defined by the parent-child relationships between attributes of the same family (formerly known as a dimension), not by user-defined hierarchies (i.e., drilling hierarchies). MicroStrategy Engine utilizes an algorithm based on attribute keys to calculate the Logical Table Size (LTS): Given the following tables: ...

Microstrategy Removing sections that do not have metric data

Removing sections that do not have metric data This is an interesting feature which might not be explored by many of us and it comes us handy. A cross join between datasets can result in rows or Group Header/Footer sections that do not have metric data. For example, a document contains two datasets. Dataset 1 contains Year and Revenue, with data for three years (2007-2009). Dataset 2 contains Year and Profit, filtered to return data for only two years (2008 and 2009). If you place Year and Profit in the Details and execute the document, it displays three rows, although no profit data exists for 2007. This is a product of the cross join between the two datasets. You do not want to see the blank line for 2007 since it does not give you any data for profit. You can select the Trim sections for which no metric value data is available check box. This removes the row for 2007, since no metric data for Profit is available for 2007. The results are shown below: ...

"System Prompt" and its uses in MicroStrategy

System Prompt and its uses in MicroStrategy WHAT IS A "SYSTEM PROMPT"? "System Prompt" is a system object that was introduced back in version 8.0.0. The object is named as "User Login" and is implemented as a prompt object. The object can be found under Public Objects > Prompts > System prompts, as shown below: Unlike ordinary prompt objects, system prompts don't require any answers from the user. When a report containing a system prompt runs, the prompt is answered automatically with the login of the user who runs the report. On the other hand, like other prompt objects, answers to system prompts are used to match caches. Therefore, users don't share caches for reports that contain system prompts. For details on how caches are matched, refer to the following MicroStrategy Knowledge Base document: KB5300-7X0-0147 - How are caches matched in MicroStrategy Intelligence Server 7.x? WHEN ARE SYSTEM PROMPTS USED? System pr...

Create a transaction services photo uploader

Create a transaction services photo uploader 1. Create a new table "photo_upload" in Tutorial warehouse database (the default location: C:\Program Files\MicroStrategy\Tutorial Reporting\TUTORIAL_DATA_7200.mdb), as shown below: 2. The 'photo_upload' table has to be pre-populated with *exactly* 10 rows of data, the values for the 'ID' column should be 1-10 and the values for the 'uploaded' column should all be 0 3. In MicroStrategy Desktop, create a freeform report "R1" based on the new table "photo_upload" in Tutorial data created at step 1, as shown below: SELECT Location, Description, ID, uploaded, numbers FROM PHOTO_UPLOAD 4.

Create an alert-based subscription in MicroStrategy Distribution Services

Create an alert-based subscription in MicroStrategy Distribution Services on Web Subscription to a report or Report Services document which will be executed when a certain conditional threshold is met based on another executing report. For example, a scheduled report executes which shows the Revenue by day for the past week. If the Revenue on any one day falls below a certain value, a subscription to another report or Report Services document can be triggered and delivered to a recipient. An alert based subscription can only be created directly on a report; however, another report or Report Services document can be delivered when the alert based subscription is triggered. Note: you need a grid report to create an alert and you cannot create if you want to create on a document with text boxes. The following example will walk through the basic steps on how to setup a subscription based on an alert like this: Follow the brief steps bel...
