Warning: PDOStatement::fetch() [<a href='pdostatement.fetch'>pdostatement.fetch</a>]: column 3 data was too large for buffer and was truncated to fit it in
问题,就是使用PDO_OCI 从Oracle 中取数据,报错或是数据被截取了,显示不完整。像这样……php
column XXX data was too large for buffer and was truncated to fit it in XXX
那么有两种方案 git
1 修改源码 oci_statement.c (估计不少人不敢动)github
php-src 中有了必定解答-修改原文件,不过 修改 ext / pdo_oci / oci_statement.c sql
531-535行 https://github.com/php/php-src/pull/59/files oracle
col->precision = scale; - col->maxlen = data_size; + col->maxlen = ( data_size + 1 ) * sizeof(utext); col->namelen = namelen; col->name = estrndup((char *)colname, namelen);
这种方式进行修改。听说是有用的 可是看过https://github.com/php/php-src/pull/59 github上并无被采纳,说明仍是有必定的问题。app
2 经过sql 处理 ide
那么,幸亏 仔细读了读了找着了https://bugs.php.net/bug.php?id=35003 函数
We found a "solution" to get it work: select cast( tbl.description AS varchar2(300) )as desc FROM database.table tbl;
使用 oracle 的 cast()函数进行转换 ,这样就能够了 IT Work !fetch

其余:关于 utext 是个啥? 或许是吧,就是转ut8用的??
