A testimonial matrix field has existed in our system for a couple of months. I've just deleted a block that's no longer needed, and am now receiving a SQL warning related to another one of the blocks. The warning occurs when I set the Max Length to anything lower than 145. Here's the warning text:
CDbCommand failed to execute the SQL statement: SQLSTATE: Warning: 1265 Data truncated for column 'field_testimonial_quotation' at row 1. The SQL statement executed was: ALTER TABLE `craft_matrixcontent_testimonialmatrix` CHANGE `field_testimonial_quotation` `field_testimonial_quotation` VARCHAR(110) NULL
I've checked all of the Entries that use this matrix block, and none of them are close to the Max Length limit.
