The string comparison in the SQL Server database is case insensitive whereas it is case sensitive in C#. Let us illustrate this with an example. Consider a user, Domain\user1. The user signs in to the Data Quality Client computer using the "user1" account, and works on a knowledge base...

If this option isn't selected, the collation is case-insensitive. That is, SQL Server considers the uppercase and lowercase versions of letters to be identical for sorting purposes. You can explicitly select case insensitivity by specifying _CI. Accent-sensitive (_AS) Distinguishes between ...
String message specifies the message as a string. When receiving messages, you can configure the task to compare the received string with a user-defined string and take action depending on the comparison. String comparison can be exact, case-sensitive or case-insensitive, or use a substring. St...
Convert(nvarchar(100), Col1) = SOME_STRING_CONSTANT -- Cannot use the index for column Col1 for some implementations.除了語意差異以外,請務必考量在 SQL Server 與 CLR 型別系統之間跨越時,對效能造成的影響。 如果是大型資料集,這類效能問題可能會決定部署應用程式的可行性。
The context module provides a case-insensitive string data type context for comparing values. SQL Server SQL Server is case insensitive by default. Adjusting the SQL Server’s collation settings can change the case sensitivity. Set the collation settings for case sensitivity at the database or ...
这些问题在更现代的版本中已经更清晰地解决,因此在标识符上调用 lower() 的性能损失已被移除。可以通过在 create_engine() 上设置“case_insensitive=False”来重新启用不区分大小写的比较。 参考:#2423 [sql] [特性] 当在insert.values() 或 update.values() 中存在不在目标表中的键时,现在“未使用的列名”...
accent-insensitive collation. Values are inserted with various case and accent differences. Because a collation isn't specified in theORDER BYclause, the first query uses the collation of the column when sorting the values. In the second query, a case-sensitive, accent-sensitive collation is spec...
SQL Server collation support. I have added a collation parameter to the Field constructor to see how this will work. Is case sensitive/insensitive comparison using explicit collations a sensible thing? Introspection not tested yet. Support for ODBC specific configuration -- see module doc in ...
The argument is case insensitive. Example: This query returns all documents where DateProp1 is greater than DateProp2 plus one hour. SELECT … FROM Document WHERE DateProp1 > DateProp2 + TimeSpan(1, 'hour') This query returns all documents where DateProp1 less one hour is greater than ...
