What could be causing it? SET LOCK_TIMEOUT 10000 However, when the user with db_datareader access runs it it takes over 20 seconds to execute. If I run this code as an administrator, it completes in less than a second. I ran the profiler while SSMS was expanding the tables which returned the code below. If a user with sysadmin does the same thing, the operation works as expected. (Microsoft SQL Server, Error: 1222) error. In this release, Azure Synapse Analytics will parse the statement successfully, but will ignore the value 1800 and continue to use the default behavior.If a user with public and db_datareader access attempts to expand the tables in SSMS 17.2 they receive a Lock request time out period exceeded. The following example sets the lock time-out period to 1800 milliseconds. This is the default behavior that is already set at the beginning of each connection. The following example sets the lock timeout to wait forever and never expire. Set the lock timeout to wait forever for a lock to be released. SET LOCK_TIMEOUT 1800 Įxamples: Azure Synapse Analytics and Analytics Platform System (PDW) B. Examples A: Set the lock timeout to 1800 milliseconds The READPAST locking hint provides an alternative to this SET option.ĬREATE DATABASE, ALTER DATABASE, and DROP DATABASE statements do not honor the SET LOCK_TIMEOUT setting. The setting of SET LOCK_TIMEOUT is set at execute or run time and not at parse time. After it is changed, the new setting stays in effect for the remainder of the connection. ![]() RemarksĪt the beginning of a connection, this setting has a value of -1. A value of 0 means to not wait at all and return a message as soon as a lock is encountered. When a wait for a lock exceeds the time-out value, an error is returned. A value of -1 (default) indicates no time-out period (that is, wait forever). Is the number of milliseconds that will pass before Microsoft SQL Server returns a locking error.
