Ansgar Becker 5a5eaabeef * Fix microseconds in MSSQL date/time data types, hidden in data and query grids. 
* Add support for microsecond precision of MSSQL date/time types in table editor, show these in "Length/Set" column
* See http://www.heidisql.com/forum.php?t=17728

+'a binary string where the first character is CHAR(128 | key_num). If '
+'an error occurs, DES_ENCRYPT() returns NULL. The 128 is added to make '
+'it easier to recognize an encrypted key. If you use a string key, '
+'key_num is 127. The string length for the result is given by this '
+'formula: new_len = orig_len + (8 - (orig_len % 8)) + 1 Each line in '

+'key_num value must be a number in the range from 0 to 9. Lines in the '

+'encrypt the message. There should be at least one space between the '

+'you do not specify any key argument to DES_ENCRYPT(). You can tell '
+'MySQL to read new key values from the key file with the FLUSH '

+'LAST_INSERT_ID() (no arguments) returns the first automatically '
+'generated value if any rows were successfully inserted or updated. '
+'This means that the returned value could be a value that was not '
+'successfully inserted into the table. If no rows were successfully '
+'inserted, LAST_INSERT_ID() returns 0. The value of LAST_INSERT_ID() '
+'will be consistent across all versions if all rows in the INSERT or '

+'AUTO_INCREMENT column and INSERT ... ON DUPLICATE KEY UPDATE updates '

+'meaningful prior to MySQL 5.1.12. For a workaround, see '
+'http://dev.mysql.com/doc/refman/5.1/en/insert-on-duplicate.html. The '

+'multiple-row INSERT statement that inserts rows into a table with its '
+'own AUTO_INCREMENT column. The value of LAST_INSERT_ID() will remain '
+'stable in the second statement; its value for the second and later '
+'rows is not affected by the earlier row insertions. (However, if you '
+'mix references to LAST_INSERT_ID() and LAST_INSERT_ID(expr), the '

+'LAST_INSERT_ID(), the changed value will be seen by statements that '

Description: 'MySQL has support for full-text indexing and searching: A full-text '

+'used only with MyISAM tables, and can be created only for CHAR, '
+'VARCHAR, or TEXT columns. A FULLTEXT index definition can be given in '
+'the CREATE TABLE statement when a table is created, or added later '
+'using ALTER TABLE or CREATE INDEX. For large data sets, it is much '
+'faster to load your data into a table that has no FULLTEXT index and '
+'then create the index after that, than to load data into a table that '
+'has an existing FULLTEXT index. Full-text searching is performed using '
+'MATCH() ... AGAINST syntax. MATCH() takes a comma-separated list that '
+'names the columns to be searched. AGAINST takes a string to search '
+'for, and an optional modifier that indicates what type of search to '
+'perform. The search string must be a literal string, not a variable or '
+'a column name. There are three types of full-text searches: A boolean '
+'search interprets the search string using the rules of a special query '
+'language. The string contains the words to search for. It can also '
+'contain operators that specify requirements such that a word must be '
+'present or absent in matching rows, or that it should be weighted '
+'higher or lower than usual. Common words such as "some" or "then" are '
+'stopwords and do not match if present in the search string. The IN '
+'BOOLEAN MODE modifier specifies a boolean search. For more '
+'information, see '
+'http://dev.mysql.com/doc/refman/5.1/en/fulltext-boolean.html. A '
+'natural language search interprets the search string as a phrase in '
+'natural human language (a phrase in free text). There are no special '
+'operators. The stopword list applies. In addition, words that are '
+'present in 50% or more of the rows are considered common and do not '
+'match. Full-text searches are natural language searches if the IN '
+'NATURAL LANGUAGE MODE modifier is given or if no modifier is given. A '
+'query expansion search is a modification of a natural language search. '
+'The search string is used to perform a natural language search. Then '
+'words from the most relevant rows returned by the search are added to '
+'the search string and the search is done again. The query returns the '
+'rows from the second search. The IN NATURAL LANGUAGE MODE WITH QUERY '
+'EXPANSION or WITH QUERY EXPANSION modifier specifies a query expansion '
+'search. For more information, see '
+'http://dev.mysql.com/doc/refman/5.1/en/fulltext-query-expansion.html. '
+'The IN NATURAL LANGUAGE MODE and IN NATURAL LANGUAGE MODE WITH QUERY '

+'designed as a number that is globally unique in space and time. Two '
+'calls to UUID() are expected to generate two different values, even if '
+'these calls are performed on two separate computers that are not '
+'connected to each other. A UUID is a 128-bit number represented by a '
+'utf8 string of five hexadecimal numbers in '
+'aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeee format: The first three numbers '
+'are generated from a timestamp. The fourth number preserves temporal '
+'uniqueness in case the timestamp value loses monotonicity (for '
+'example, due to daylight saving time). The fifth number is an IEEE 802 '
+'node number that provides spatial uniqueness. A random number is '
+'substituted if the latter is not available (for example, because the '
+'host computer has no Ethernet card, or we do not know how to find the '
+'hardware address of an interface on your operating system). In this '
+'case, spatial uniqueness cannot be guaranteed. Nevertheless, a '
+'collision should have very low probability. Currently, the MAC address '
