Good source control of both source database and the Analysis Services project helps to track what changed to cause the problems and allows reversion to last known good.Īfter a while you become conditioned to the way it works and I should say that development is not normally as frustrating as this article might suggest (although Tabular has plenty of other annoyances to offer). ConclusionĪnalysis Services Tabular does its best to make enterprise development difficult. There is another reason not mentioned in the error message: the table is marked as a date table and the column mentioned is the date column. Error returned: ‘Column ‘Date’ in Table ‘Date’ contains blank values and this is not allowed for columns on the one side of a many-to-one relationship or for columns that are used as the primary key of a table.Īnd yet the column mentioned is not involved in a relationship and is not a primary key (nor marked as unique). Blank values not allowed for…įailed to save modifications to the server. On the other hand, incoming date-time values will be coerced into a numeric column without error. In this example the processing failed when character values were supplied for a numeric destination column in the Tabular model. The exception is only raised once Analysis Services finds some data that it cannot manipulate to fit the destination data type. If the incoming data can be coerced into the destination type there will also be no error. If a column has the wrong data type but has no data (only nulls) there will be no error. It only checks the incoming data, if any (according to my experiments). Note that Tabular does not check source data types from column metadata, hence the emphasis above. Meaning Some column of some table contains data of the wrong typeĪs usual, there is no indication of which column or which table. (Exception from HRESULT: 0x80020005 (DISP_E_TYPEMISMATCH)) Error returned: ‘OLE DB or ODBC error: Type mismatch. A column is missing from one of these tables… but which? All tables repeat the same error messageįailed to save modifications to the server. This at least states which column is missing but it doesn’t say which table which can still lead to a bit of hunting. Meaning: one of the referenced columns could not be found in the source table or view. Error returned: ‘The ‘Amount’ column does not exist in the rowset. “The xxx column does not exist in the rowset”įailed to save modifications to the server. The only way to get the designer interface to reveal which table it is is to attempt to process each item individually until the miscreant is found. It is left to the user to find which item is unavailable. A table near the end of the list doesn’t exist in the source… but none of the copious error paraphernalia in these dialogs tells you that. Each item has an “Error description link”, but the message behind each link is exactly the same (see below). Which table or view, though? Although the processing dialog box lists each item on its own line, if one item fails then all items are marked as failures, which gives no hint as to which one is the root cause. The source table or view itself cannot be found. Well, it isn’t: the “key” and “rows” are something internal to Analysis Services – and Tabular does not check referential integrity in any case. The term “key”, which is prevalent in data warehousing, and the phrase “rows in the table” strongly suggest that the problem is some mismatched value in the data. Perhaps the table or view was renamed or dropped or Analysis Services does not have select permission on it. Meaning The table or view does not exist in the source. Error returned: ‘OLE DB or ODBC error: The key didn’t match any rows in the table. These are messages shown in the designer dialogs but the same messages are returned when processing on a server.įailed to save modifications to the server. This is a short list of some of the more head-scratching error messages that occur when processing a Tabular model (Version 1500).
