Length

Use this field to specify the length (byte count) of the columns based on the specified data type:

CHARACTER
Length of the fixed-length character string, which can range from 1 to 254.

VARCHAR
Maximum length of the varying-length character string, which can range from 1 to 4000.

BLOB
Maximum length of the BLOB string, which can range from 1 to 2147483647. If a LOB unit of Kbytes, Mbytes, or Gbytes is specified in the LOB unit box, the maximum value of Length is limited as follows:

Kbytes
The maximum value for this field is 2097152. Each KB is equivalent to 1024 bytes, so the maximum length in bytes is 1024 times the integer value you specify in this field.

Mbytes
The maximum value for this field is 2048. Each MB is equivalent to 1048576 bytes, so the maximum length in bytes is 1048576 times the integer value you specify in this field.

Gbytes
The maximum value for this field is 2. Each GB is equivalent to 1073741824 bytes, so the maximum length in bytes is 1073741824 times the integer value you specify in this field.

CLOB
Maximum length of the CLOB string, which can range from 1 to 2147483647. If a LOB unit of Kbytes, Mbytes, or Gbytes is specified in the LOB unit box, the maximum value of Length is limited as follows:

Kbytes
The maximum value for this field is 2097152. Each KB is equivalent to 1024 bytes, so the maximum length in bytes is 1024 times the integer value you specify in this field.

Mbytes
The maximum value for this field is 2048. Each MB is equivalent to 1048576 bytes, so the maximum length in bytes is 1048576 times the integer value you specify in this field.

Gbytes
The maximum value for this field is 2. Each GB is equivalent to 1073741824 bytes, so the maximum length in bytes is 1073741824 times the integer value you specify in this field.

DBCLOB
Maximum length of the DBCLOB string, which can range from 1 to 1073741823 double-byte characters. If a LOB unit of Kbytes, Mbytes, or Gbytes is specified in the LOB unit box, the maximum value of Length is limited as follows:

Kbytes
The maximum value for this field is 1048576. Each KB is equivalent to 1024 bytes, so the maximum length in double bytes is 1024 times the integer value you specify in this field.

Mbytes
The maximum value for this field is 1024. Each MB is equivalent to 1048576 bytes, so the maximum length in double bytes is 1048576 times the integer value you specify in this field.

Gbytes
The maximum value for this field is 1. Each GB is equivalent to 1073741824 bytes, so the maximum length in double bytes is 1073741824 times the integer value you specify in this field.

GRAPHIC
Length of the fixed-length graphic string, which can range from 1 to 127. If the length is not specified, a length of 1 is assumed.

VARGRAPHIC
Maximum length of the varying-length graphic string, which can range from 1 to 2000.
