Crawling all the tables in a schema
When you create a database data source, you usually select one table or one view to crawl.
Alternatively, you can choose to crawl all the tables in a schema.
When you use this option, NOW Privacy:
crawls every table that has a suitable primary key or unique index
ignores tables that don’t have either of those
ignores views
You can use sampling in this mode too.
A suitable primary key or unique index must:
be on a single column (that is, not composite key)
not be nullable
have a supported data type
For MySQL you can use any data type except:
blob
tinyblob
mediumblob
longblob
varbinary
binary
geometry
geomcollection
linestring
multilinestring
multipolygon
point
multipoint
polygon
time
For Microsoft SQL Server, you can use any data type except:
binary
varbinary
image
cursor
sql_variant
table
hierarchyid
geography
geometry
timestamp
datetimeoffset
xml
