We know that character fields can contain uppercase and lowercase characters. How can we ignore case-insensitive characters in SQL fuzzy queries?
For example, select * From tablename where fieldb like 'a % '. You want to obtain all records starting with 'A' or 'A.
The following explains how to use 'sort sequence ':
* The default value of the system value qsrtseq is * hex;
* The default value of the srtseq parameter in the user profile table is * sysval;
* In strsql and crtsqlxxx, the default srtseq parameter is * job.
Therefore, the default sort Sequence Value of an OS/400 job is * hex, which means that every character in the orders table has
The relative order and weight of each character. For example, the weight of the character 'a' is 'c1 ', and the weight of the character 'a' is '81'. Therefore, any
The Comparison Between 'A' and 'A' is considered to be different. If you want to compare the two to be equivalent to the character 'a' and 'A', you need
Set 'sort sequence 'to * langidshr to the same weight. The setting method is as follows:
1. strsql
2. f13-Service
3. 1. Change the dialog property.
4. Go down to the page and find 'sort sequence and change it to * langidshr
5. Press the Enter key twice.
6. Run an SQL statement, for example:
Select * from file where field1 like 'a % 'or
Select * from file where field1 like 'a %'
7. Check the query results and you will find that all records whose field1 fields start with 'A' and 'A' are searched.
