For database design, you have to consider that the column sizes have to be defined in bytes, not in characters.
对于数据库设计，必须考虑到列大小是按照字节数定义的，而不是按照字符数。
FOLD_AFTER, FOLD_BEFORE - When a record exceeds the number of characters available for a row, this option allows you to decide where to fold the record-after or before the current column.
FOLD_AFTER, FOLD _ BEFORE-当某条记录超过一行的有效字符数时，该选项可让您决定在何处折叠该记录————在当前列之前还是之后。
Since a graphic character is always 2 bytes long, the maximum graphic length that can be indexed is 510 graphic characters, and the column can be defined as VARGRAPHIC (510).
因为图形化字符总是2字节长的，所以可以建立索引的最大图形化字符长度是510个字符，列可以定义为VARGRAPHIC (510)。
The column LASTNAME is formatted with "A6," which restricts the column values to a maximum of six characters.
用格式“ A6 ”对列lastname进行格式化，从而将列值限制在最大为6个字符。
Therefore, the maximum number of characters that can be stored in the column might be reduced if non-ASCII characters are involved.
因此，如果涉及非ascii字符，那么列中可以存储的最大字符数可能会减少。
TRUNCATED - When the column value exceeds the column width, truncate the exceeding characters.
TRUNCATED-当列值超过列的宽度时，截断超出的字符。
If you use a nullable VARCHAR column and only ASCII characters (UTF-8 format 1 byte per character) involved, the maximum character length that can be indexed is 1021 characters.
如果使用可空的varchar列并只涉及ASCII字符(在utf - 8格式中每字符1字节)，那么可以建立索引的最大字符长度是1021个字符。
A delimited ASCII (del) file is a stream of ASCII characters; rows in the data stream are separated by row delimiters, and column values within a row are separated by column delimiters.
分隔的ASCII (DEL)文件是ASCII字符流；数据流中的行由行分隔符分隔，而行中的列值由列分隔符分隔。
Change the expression of the JOB_DESC column to display only the first 50 characters, as described above.
修改job_desc列的表达式，使其只显示前50个字符，如上所述。
For example, if the column has a type of VARCHAR (256), results that are longer than 256 characters result in a failed flow and an SQL error.
例如，如果列的类型为VARCHAR(256)，大于256个字符的结果将导致失败的流和SQL错误。
However, if the column is a character data type and contains only numeric characters, you can indicate this by setting the NUMERIC_STRING option to 'y.'
然而，如果列是字符数据类型，并且只包含数字字符，那么可以通过将NUMERIC_STRING选项设置为“Y”来表明这一点。
For our example, item_id is a char column that stores only numeric characters, as we indicate in the following statement.
对于我们的例子，item_id是一个char列，它只存储数字字符，如以下语句所示。
The name column contains the name of the optimization profile and may contain an alphanumeric string of up to 128 characters.
name列包含优化概要文件的名称，还可能包含最多由128个字符组成的字母数字式字符串。
For example, if you store the following five Chinese characters in UTF-8, you need to define a table column at minimum with char (15).
例如，如果以utf - 8格式存储以下5个中文字符，那么至少需要用CHAR(15)定义一个表列。
Given that you know only the UCS-2 hex-code, there is another method for entering Unicode characters in a UTF-8 column.
如果只知道UCS- 2十六进制编码，还有另一种方法可以在utf - 8列中输入unicode字符。
If you know the UTF-8 encoding of a character, you can also use this method to enter Unicode characters in a char or VARCHAR column.
如果知道字符的UTF - 8编码，也可以用这种方法在CHAR或varchar列中输入unicode字符。
In addition, the vendorName column is stored as a string of characters with a maximum length of 64.
另外，vendorname列以字符串类型保存，最大长度为64。
You can use UTF characters as table names or column names in a database.
您可以使用UT f字符作为数据库中的表名或列名。

For ipload, database, table and column names cannot exceed 18 characters.
