conditions are valid. Here we use the facet syntax of SOLR, which I understand as a shard or a categorical query. The result of using the Facet field query is that in the Facetfields field of the return value, he lists all the brand's IDs and returns a keyvalue that returns all the brands and the corresponding number of vehicle sources. The number of vehicles with a quantity greater than 0 is the corresponding brand data in the region.isolroperations(); //Find a cityIsolrquery q1 =NewSolrqueryb

Pivot row and column conversions in SQLThis article is guided by: in T-SQL statements, the pivot operator is used to rotate or pivot data between columns and rows, and the pivot command can implement a column change of a data table while performing an aggregation operation, and Unpivot, in contrast, implements row-to-column data.Pivot rotates table-valued expressions by converting unique values in one column of an expression to multiple columns in the output, and performs aggregations if necessa
Pivot rotates a table-valued expression by converting the unique value in a column of an expression to multiple columns in the output, and performs an aggregation if necessary on any remaining column values that are required in the final output. Unpivot performs the opposite operation with Pivot, converting the column of the table-valued expression to the column value.

The algorithm of this paper is based on Sase language. The language is not described in detail, and only the pattern matching algorithm is described here. 1. Method based on query plan 1.1 basic query plan
The query plan in Sase consists of a subset of 6 operators:

MoD () is the remainder function
MoD (15, 7) = 1
MoD (15,-7) =-6
MoD (-15, 7) = 6
MoD (-15,-7) =-1
15 = 7 * 2 + 1
15 = (-7) * (-3) + (-6)
-15 = 7 * (-3) + 6
-15 = (-7) *2 + (-1)
The divisor, divisor, quotient, and remainder are respectively recorded as M, N, p, q (M, n, p, n >= 0)
Then there are:
m = n * p1 + q1
m = (-N) * (-P2) + (-Q2)
-M = n * (-P3) + Q3
-M = (-N) * P4 + (-Q4)
The positive and negative signs of divisor, divisor, quotient and remai
