Convert deadlocks: Two or more processes hold a shared lock on the same resource in the transaction and want to upgrade it to an exclusive lock, but no one can upgrade until the other process releases the shared lock, as Some scenarios in SQL

index is useless for expressions that do not meet the SARG format. After introducing SARG, let's summarize the experiences of using SARG and drawing different conclusions from some materials in practice: 1. Whether the Like statement belongs to the SARG depends on the type of the wildcard used. -- Example:Name like 'zhang % '--, which belongs to SARG -- And:Name like '% Zhang' --, does not belong to SARG.
