Me gustaría ofrecer una versión más fácil de leer de la respuesta de @Daniel Renshaw:
DECLARE @CatalogName VARCHAR(MAX)
SET @CatalogName = 'FTS_Demo_Catalog'
SELECT
DATEADD(ss, FULLTEXTCATALOGPROPERTY(@CatalogName,'PopulateCompletionAge'), '1/1/1990') AS LastPopulated
,(SELECT CASE FULLTEXTCATALOGPROPERTY(@CatalogName,'PopulateStatus')
WHEN 0 THEN 'Idle'
WHEN 1 THEN 'Full Population In Progress'
WHEN 2 THEN 'Paused'
WHEN 3 THEN 'Throttled'
WHEN 4 THEN 'Recovering'
WHEN 5 THEN 'Shutdown'
WHEN 6 THEN 'Incremental Population In Progress'
WHEN 7 THEN 'Building Index'
WHEN 8 THEN 'Disk Full. Paused'
WHEN 9 THEN 'Change Tracking' END) AS PopulateStatus
Resultados:
LastPopulated PopulateStatus
