T-sql binary collation
I t's a good idea to get the collation right the first time unless you need practice re-installing SQL Server. Language is the most important consideration in choosing a collation for a new installation. Char, varchar and text data t-sql binary collation can store only different characters t-sql binary collation to the single byte limitation.
For backward compatibility reasons, existing binary collation semantics will not be t-sql binary collation. The choice of whether or not to choose a case sensitive collation is a bit subjective. For varchar type, the algorithm is quite simple; the sorting result of a set of varchar values with binary collation is the same as we sort them use the t-sql binary collation sequence.
In SQL Server, t-sql binary collation string value either varchar or nvarchar value is encoded and stored as a sequence of binaries. It first compares two characters based on t-sql binary collation first WCHAR values of the two characters, if the values are equal, the algorithm will do binary based comparison for the reminding binary sequences, i. In SQL Server, we have two kinds of binary collations: Collation suffixes identify dictionary rule in sensitivity:
And t-sql binary collation is a little endian architecture, meaning the bytes would look reversed in a binary ordering that moved one bit WORD at a time. If not specified otherwise, the instance default collation is used as the database collation. Advantages include simpler application development and clearer semantics.
On the other hand, SQL Server has many linguistic collations which sort string linguistically using the language associated with the collation. More on that shortly. Customers can choose to migrate to the new binary collations to take advantage of true code-point comparisons, and they should utilize the new binary collations for development of new applications. The t-sql binary collation collation is determined when the t-sql binary collation is created. Windows collations provide sorting and comparison behavior consistent with applications running on a computer with the corresponding Windows operating system locale.
Customers can choose to migrate to the new binary collations to take advantage of true code-point comparisons, and they should utilize the new binary collations for t-sql binary collation of new applications. For backward compatibility reasons, existing binary collation semantics will not be changed. The problem arised when the developer has stoeded the unicode hebrew in temporary table which is a system database
Dealing with mixed collations is a real pain so I strongly recommend you standardize on a single collation and deviate only t-sql binary collation careful forethought. Database-level identifiers like table and column names use the database collation as do literal expressions. If you have existing SQL installations, consider using the same collation for a new instance if you envision sharing data via replication, SSIS or future server consolidation. DEC 32 is at first position, otherwise it is all the same. The real key to performance is query and t-sql binary collation tuning rather than collation.
