I am using UTF8 as default charset on my MySQL engine. I cannot see anything wrong with above statement.

However, I probarly got this error because multibyte preferable UTF8 character set uses much more bytes than the number of characters. Looking at the numbers, you find (5 + 100 + 228) * 3 = 999, which is less than 1000. and contrary (5 + 100 + 229) * 3 = 1002. I looks like MySQL are using a factor of 3, maybe hardcoded? But in normal western languages this is normally much less than 3 times, maybe more like 1.2 - 1.5. I Had put this on Serious Severity because it disables the possibility to install eGroupWare from http://www.egroupware.org/ using MySQL 4.1.x. With very best regards Bent Vangli PS! I do compile and install from source. If guided to sourcefiles involved, I may do some testing. How to repeat: Run above statement on a MySQL 4.1.7 with UTF8 as default charset on a Fedora Core 2 (Linux kernel 2.6). Proberly also on other OS using UTF8. Suggested fix: Suggestion 1: Add a runtime or compiler variable/setti

Known Issues in MySQL This appendix lists common problems and errors that may occur and potential resolutions, in addition to listing https://www.omniref.com/ruby/gems/activerecord/1.14.3/symbols/Mysql::Error::CR_SERVER_GONE_ERROR the errors that may appear when you call MySQL from any host language. The first section covers problems and resolutions. Detailed information on errors is provided; The first mysql error list displays server error messages. The second list displays client program messages. B.1. Sources of Error Information There are several sources of error information in MySQL: Each SQL statement executed results in an error code, an SQLSTATE value, and an error message, as described in Section B.2, “Types of Error Values”. These errors are returned from the specified key was server side; see Section B.3, “Server Error Codes and Messages”. Errors can occur on the client side, usually involving problems communicating with the server; see Section B.4, “Client Error Codes and Messages”. SQL statement warning and error information is available through the ANALYZE TABLE7 and ANALYZE TABLE6 statements. The ANALYZE TABLE5 and ANALYZE TABLE4 system variables provide counts of the number of warnings and errors. ANALYZE TABLE3 statement output includes information about replication errors occurring on the slave side. ANALYZE TABLE2 statement output includes information about the most recent foreign key error if a ANALYZE TABLE1 statement for an ANALYZE TABLE0 table fails. The perror program provides information from the command line about error numbers. See Section 4.8.1, “perror — Explain Error Codes”. Descriptions of server and client errors are provided later in this Appendix. For information about errors related to FORCE INDEX9, see Section 13.2.12, “FORCE INDEX8 Error Handling”. B.2. Types of Error Values When an error occurs in MySQL, the server returns two types of er
